Muhammad in the context of Innocence of Muslims

The historiography of early Islam is the secular scholarly literature on the early history of Islam during the 7th century, from Muhammad's first purported revelations in 610 until the disintegration of the Rashidun Caliphate in 661, and arguably throughout the 8th century and the duration of the Umayyad Caliphate, terminating in the incipient Islamic Golden Age around the beginning of the 9th century.

Muslims developed methodologies such as the "science of biography" and the "science of hadith" to evaluate the reliability of these narratives, while prominent figures like Ibn Khaldun introduced critical historiographical methods, emphasizing the importance of context and the systematic evaluation of historical data.

Sunni Islam is the largest branch of Islam and the largest religious denomination in the world. It holds that Muhammad did not appoint any successor and that his closest companion Abu Bakr (r. 632–634) rightfully succeeded him as the caliph of the Muslim community, being appointed at the meeting of Saqifa. This contrasts with the Shia view, which holds that Muhammad appointed Ali ibn Abi Talib (r. 656–661) as his successor. Nevertheless, Sunnis revere Ali, along with Abu Bakr, Umar (r. 634–644) and Uthman (r. 644–656) as 'rightly-guided caliphs'.

The term Sunni means those who observe the sunna, the practices of Muhammad. The Quran, together with hadith (especially the Six Books) and ijma (scholarly consensus), form the basis of all traditional jurisprudence within Sunni Islam. Sharia legal rulings are derived from these basic sources, in conjunction with consideration of public welfare and juristic discretion, using the principles of jurisprudence developed by the four legal schools: Hanafi, Hanbali, Maliki and Shafi'i.

The early Muslim conquests or early Islamic conquests (Arabic: الْفُتُوحَاتُ الإسْلَامِيَّة, romanized: al-Futūḥāt al-ʾIslāmiyya), also known as the Arab conquests, were a series of wars initiated in the 7th century by Muhammad, the prophet of Islam. He established the first Islamic state in Medina, Arabia that expanded rapidly under the Rashidun Caliphate and the Umayyad Caliphate, culminating in Muslim rule being established in Asia, Northern Africa, and Southern Europe over the following century. According to historian James Buchan: "In speed and extent, the first Arab conquests were matched only by those of Alexander the Great, and they were more lasting." At their height, the territory that was conquered by the Arab Muslims stretched from Iberia (at the Pyrenees) in the west to India (at Sind) in the east; Muslim control spanned Sicily, most of the Middle East and North Africa, and the Caucasus and Central Asia.

Among other drastic changes, the early Muslim conquests brought about the collapse of the Sasanian Empire and great territorial losses for the Byzantine Empire. Explanations for the Muslim victories have been difficult to discover, primarily because only fragmentary sources have survived from the period. American scholar Fred McGraw Donner suggests that Muhammad's establishment of an Islamic state in Arabia coupled with ideological (i.e., religious) coherence and mobilization constituted the main factor that propelled the early Muslim armies to successfully establish, in the timespan of roughly a century, one of the largest empires in history. Estimates of the total area of the combined territory held by the early Muslim polities at the conquests' peak have been as high as 13,000,000 square kilometres (5,000,000 sq mi). Most historians also agree that, as another primary factor determining the early Muslim conquests' success, the Sasanians and the Byzantines were militarily and economically exhausted from decades of warfare against each other.

Islam is an Abrahamic monotheistic religion based on the Quran and the teachings of Muhammad. Adherents of Islam are called Muslims, who are estimated to number 2 billion worldwide and are the world's second-largest religious population, after Christianity.

Muslims believe that there is a primordial faith that was revealed many times through earlier prophets and messengers, including Adam, Noah, Abraham, Moses, and Jesus, and they believe that Islam is the universal and complete version of this faith. Muslims consider the Quran to be the verbatim word of God and the unaltered, final revelation. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (the Torah), the Zabur (Psalms), and the Injil (Gospel). They believe that Muhammad is the main and final of God's prophets, through whom the religion was completed. The teachings and normative examples of Muhammad, called the Sunnah, documented in accounts called the hadith, provide a constitutional model for Muslims. Islam is based on the belief in the oneness and uniqueness of God (tawhid), and belief in an afterlife (akhirah) with the Last Judgment—wherein the righteous will be rewarded in paradise (jannah) and the unrighteous will be punished in hell (jahannam). The Five Pillars, considered obligatory acts of worship, are the Islamic oath and creed (shahada), daily prayers (salah), almsgiving (zakat), fasting (sawm) in the month of Ramadan, and a pilgrimage (hajj) to Mecca. Islamic law, sharia, touches on virtually every aspect of life, from banking and finance and welfare to men's and women's roles and the environment. The two main religious festivals are Eid al-Fitr and Eid al-Adha. The three holiest sites in Islam are Masjid al-Haram in Mecca, Prophet's Mosque in Medina, and al-Aqsa Mosque in Jerusalem.

A caliphate (Arabic: خلافة, romanized: khilāfa [xiˈlaːfa]) is an institution or public office under the leadership of an Islamic steward with the title of caliph (/ˈkælɪf, ˈkeɪ-/; خليفة khalīfa [xaˈliːfa], pronunciation), a person considered a political–religious successor to the Islamic prophet Muhammad and a leader of the entire Muslim world (ummah). Historically, the caliphates were polities based on Islam which developed into multi-ethnic trans-national empires.

During the medieval period, three major caliphates succeeded each other: the Rashidun Caliphate (632–661), the Umayyad Caliphate (661–750), and the Abbasid Caliphate (750–1517). In the fourth major caliphate, the Ottoman Caliphate, the rulers of the Ottoman Empire claimed caliphal authority from 1517 until the Ottoman Caliphate was formally abolished as part of the 1924 secularisation of Turkey. The Sharif of Mecca then claimed the title, but this caliphate fell quickly after its conquest by the Sultanate of Nejd (the predecessor of modern-day Saudi Arabia), leaving the claim in dormancy. Throughout the history of Islam, a few other Muslim states, almost all of which were hereditary monarchies, have claimed to be caliphates.

Bahrain, officially the Kingdom of Bahrain, is an island country in West Asia. Situated on the Persian Gulf, it comprises a small archipelago of 50 natural islands and an additional 33 artificial islands, centred on Bahrain Island, which makes up around 83 percent of the country's landmass. Bahrain is situated between Qatar and the northeastern coast of Saudi Arabia, to which it is connected by the King Fahd Causeway. The population is 1,588,670 as of 2024, of whom 739,736 (46.6% of the population) are Bahraini nationals, and 848,934 are expatriates (53.4% of the population). Bahrain spans some 760 square kilometres (290 sq mi) and is the third-smallest nation in Asia after Maldives and Singapore. The capital and largest city is Manama.

The area that straddles the present-day territory of Bahrain was once the site of the ancient Dilmun civilisation. It has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to be influenced by Islam, during the lifetime of Muhammad in 628. Following a period of Arab rule, Bahrain was ruled by the Portuguese Empire from 1521 until 1602, when they were expelled by Shah Abbas the Great of the Safavid Iran. In 1783, the Bani Utbah and allied tribes captured Bahrain from Nasr Al-Madhkur. It has since been ruled by the Al Khalifa royal family, with Ahmed al Fateh as Bahrain's first hakim.

The Rashidun Caliphate (Arabic: ٱلْخِلَافَةُ ٱلرَّاشِدَةُ, romanized: al-Khilāfah ar-Rāšidah) is the early Islamic polity led by the first four successive caliphs (lit. "successors") Abu Bakr, Umar, Uthman and Ali, collectively the Rashidun, or "Rightly Guided" caliphs. These early caliphs led the Muslim community from the death of the Islamic prophet Muhammad in 632 CE to the foundation of the Umayyad Caliphate in 661 CE.

The title Rashidun stems from the Sunni Islamic belief that the caliphs were "rightly guided". Endowed with superior piety and wisdom, their era is regarded in Sunni Islam as a "golden age", second only to the lifetime of the Prophet Muhammad in sanctity and in providing moral and religious guidance. Sunni Muslims consider the "rightly guided" reign of the first four caliphs as a model to be followed and emulated from a religious point of view. The term Rashidun is not used by Shia Muslims, who make up 10–15% of the global Muslim population, as they reject the rule of the first three caliphs as illegitimate.

The Umayyad Caliphate or Umayyad Empire (US: /uːˈmaɪæd/; Arabic: ٱلْخِلَافَة ٱلْأُمَوِيَّة, romanized: al-Khilāfa al-Umawiyya) was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty from 661 to 750. It succeeded the Rashidun Caliphate, of which the third caliph, Uthman ibn Affan, was also a member of the clan. The Umayyad family established dynastic, hereditary rule with Mu'awiya ibn Abi Sufyan, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power was eventually claimed by Marwan ibn al-Hakam, from another branch of the clan. Syria remained the Umayyads' core power base thereafter, with Damascus as their capital.

The Umayyads continued the Muslim conquests, conquering Ifriqiya, Transoxiana, Sind, the Maghreb and Hispania (al-Andalus). At its greatest extent, the Umayyad Caliphate covered 11,100,000 km (4,300,000 sq mi), making it one of the largest empires in history in terms of area. The dynasty was toppled by the Abbasids in 750. Survivors of the dynasty established themselves in Córdoba which, in the form of an emirate and then a caliphate, became a world center of science, medicine, philosophy and invention during the Islamic Golden Age.

The Hijri calendar (Arabic: ٱلتَّقْوِيم ٱلْهِجْرِيّ, romanized: al-taqwīm al-hijrī), also known in English as the Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual fasting and the annual season for the great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Syriac month-names used in the Levant and Mesopotamia (Iraq, Syria, Jordan, Lebanon and Palestine), but the religious calendar is the Hijri one.

This calendar enumerates the Hijri era, whose epoch was established as the Islamic New Year in 622 CE. During that year, Muhammad and his followers migrated from Mecca to Medina and established the first Muslim community (ummah), an event commemorated as the Hijrah. In the West, dates in this era are usually denoted AH (Latin: Anno Hegirae, lit. 'In the year of the Hijrah'). In Muslim countries, it is also sometimes denoted as H from its Arabic form (سَنَة هِجْرِيَّة, abbreviated ھ). In English, years prior to the Hijra are denoted as BH ("Before the Hijra").

The terms Islamic world and Muslim world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs, politics, and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense.

The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology during the Islamic Golden Age. Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam. The Islamic conquests, which culminated in the Caliphate being established across three continents (Asia, Africa, and Europe), enriched the Muslim world, achieving the economic preconditions for the emergence of this institution owing to the emphasis attached to Islamic teachings. In the modern era, most of the Muslim world came under European colonial domination. The nation states that emerged in the post-colonial era have adopted a variety of political and economic models, and they have been affected by secular as well as religious trends.

Islam is India's second-largest religion, with 14.2% of the country's population, or approximately 172.2 million people, identifying as adherents of Islam in a 2011 census. India has the third-largest number of Muslims in the world. Most of India's Muslims are Sunni, with Shia making up around 15% of the Muslim population.

Islam first spread in southern Indian communities along the Arab coastal trade routes in Gujarat and in Malabar Coast shortly after the religion emerged in the Arabian Peninsula. Later, Islam arrived in the northern inland of Indian subcontinent in the 7th century when the Arabs invaded and conquered Sindh. It arrived in Punjab and North India in the 12th century via the Ghaznavids and Ghurids conquest and has since become a part of India's religious and cultural heritage. The Barwada Mosque in Ghogha, Gujarat built before 623 CE, Cheraman Juma Mosque (629 CE) in Methala, Kerala and Palaiya Jumma Palli (or The Old Jumma Masjid, 628–630 CE) in Kilakarai, Tamil Nadu are three of the first mosques in India which were built by seafaring Arab merchants. According to the legend of Cheraman Perumals, the first Indian mosque was built in 624 CE at Kodungallur in present-day Kerala with the mandate of the last ruler (the Tajudeen Cheraman Perumal) of the Chera dynasty, who converted to Islam during the lifetime of the Islamic prophet Muhammad (c. 570–632). Similarly, Tamil Muslims on the eastern coasts also claim that they converted to Islam in Muhammad's lifetime. The local mosques date to the early 700s.

Fiqh ([fiːk]; Arabic: فقه [fiqh]) is the term for Islamic jurisprudence. Fiqh is often described as the style of human understanding, research and practices of the sharia; that is, human understanding of the divine Islamic law as revealed in the Quran and the sunnah (the teachings and practices of the Islamic prophet Muhammad and his companions). Fiqh expands and develops Shariah through interpretation (ijtihad) of the Quran and Sunnah by Islamic jurists (ulama) and is implemented by the rulings (fatwa) of jurists on questions presented to them. Thus, whereas sharia is considered immutable and infallible by Muslims, fiqh is considered fallible and changeable. Fiqh deals with the observance of rituals, morals and social legislation in Islam as well as economic and political system. In the modern era, there are four prominent schools (madh'hab) of fiqh within Sunni practice, plus two (or three) within Shi'a practice. A person trained in fiqh is known as a faqīh (pl.: fuqaha).

Figuratively, fiqh means knowledge about Islamic legal rulings from their sources. Deriving religious rulings from their sources requires the mujtahid (an individual who exercises ijtihad) to have a deep understanding in the different discussions of jurisprudence.

In the Islamic study of hadith, an isnād (chain of transmitters, or literally "supporting"; Arabic: اِسْناد) refers to a list of people who passed on a tradition, from the original authority to whom the tradition is attributed to, to the present person reciting or compiling that tradition. The tradition an isnad is associated with is called the matn. Isnads are an important feature of the genre of Islamic literature known as hadith and are prioritized in the process that seeks to determine if the tradition in question is authentic or inauthentic.

According to the traditional Islamic view, the tradition of the hadith sciences has succeeded in the use of isnads to distinguish between authentic and inauthentic traditions going back to Muhammad and his companions. The contemporary view in modern hadith studies, however, is that isnads were commonly susceptible to forgery and so had to be scrutinized before being used to guarantee the transmission of a tradition.

The issue of succession following the death of the Islamic prophet Muhammad is the central issue in the schisms that divided the early Muslim community in the first century of Islamic history into numerous schools and branches. The two most prominent branches that emerged from these divisions are Sunni and Shia as well as Ibadi branches of Islam. Sunni Islam and Ibadi Islam asserts that Abu Bakr rightfully succeeded Muhammad through a process of election. In contrast, Shia Islam maintains that Ali ibn Abi Talib was Muhammad's designated successor.

These differing viewpoints on succession stem from varying interpretations of early Islamic history and the hadiths, which are the recorded sayings of Muhammad. Sunni Muslims contend that Muhammad did not explicitly appoint a successor, leaving the choice of leadership to the Muslim community. They recognize the legitimacy of Abu Bakr's rule, who was elected at Saqifah, as well as that of his successors, collectively known as the Rashidun caliphs.

Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country in West Asia. Located in the center of the Middle East, it covers the bulk of the Arabian Peninsula and has a land area of about 2,150,000 km (830,000 sq mi), making it the fifth-largest country in Asia, the largest in the Middle East, and the twelfth-largest in the world. It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Bahrain, Qatar and the United Arab Emirates to the east; Oman to the southeast; and Yemen to the south. The Gulf of Aqaba in the northwest separates Saudi Arabia from Egypt and Israel. Saudi Arabia is the only country with a coastline along both the Red Sea and the Persian Gulf, and most of its terrain consists of arid desert, lowland, steppe, and mountains. The capital and largest city is Riyadh; other major cities include Jeddah and the two holiest cities in Islam, Mecca and Medina. With a population of almost 32.2 million, Saudi Arabia is the fourth most populous country in the Arab world.

Pre-Islamic Arabia, the territory that constitutes modern-day Saudi Arabia, was the site of several ancient cultures and civilizations; the prehistory of Saudi Arabia shows some of the earliest traces of human activity outside Africa. Islam emerged in what is now Saudi Arabia in the early seventh century. Islamic prophet Muhammad united the population of the Arabian Peninsula and created a single Islamic religious polity. Following his death in 632, his followers expanded Muslim rule beyond Arabia, conquering territories in North Africa, Central, South Asia and Iberia within decades. Arab dynasties originating from modern-day Saudi Arabia founded the Rashidun (632–661), Umayyad (661–750), Abbasid (750–1517), and Fatimid (909–1171) caliphates, as well as numerous other Muslim states in Asia, Africa, and Europe.

The Fatimid Caliphate (/ˈfætɪmɪd/; Arabic: الخلافة الفاطمیّة, romanized: al-Khilāfa al-Fāṭimiyya), also known as the Fatimid Empire, was a caliphate extant from the tenth to the twelfth centuries CE under the rule of the Fatimids, an Isma'ili Shi'a dynasty. Spanning a large area of North Africa and West Asia, it ranged from the western Mediterranean in the west to the Red Sea in the east. The Fatimids traced their ancestry to the Islamic prophet Muhammad's daughter Fatima and her husband Ali, the first Shi'a imam. The Fatimids were acknowledged as the rightful imams by different Isma'ili communities as well as by denominations in many other Muslim lands and adjacent regions. Originating during the Abbasid Caliphate, the Fatimids initially conquered Ifriqiya (roughly present-day Tunisia and north-eastern Algeria). They extended their rule across the Mediterranean coast and ultimately made Egypt the center of the caliphate. At its height, the caliphate included—in addition to Egypt—varying areas of the Maghreb, Sicily, the Levant, and the Hejaz.

Between 902 and 909, the foundation of the Fatimid state was realized under the leadership of da'i (missionary) Abu Abdallah, whose conquest of Aghlabid Ifriqiya with the help of Kutama forces paved the way for the establishment of the Caliphate. After the conquest, Abdallah al-Mahdi Billah was retrieved from Sijilmasa and then accepted as the Imam of the movement, becoming the first Caliph and founder of the dynasty in 909. In 921, the city of al-Mahdiyya was established as the capital. In 948, they shifted their capital to al-Mansuriyya, near Kairouan. In 969, during the reign of al-Mu'izz, they conquered Egypt, and in 973, the caliphate was moved to the newly founded Fatimid capital of Cairo. Egypt became the political, cultural, and religious centre of the empire and it developed a new and "indigenous Arabic culture". After its initial conquests, the caliphate often allowed a degree of religious tolerance towards non-Shi'a sects of Islam, as well as to Jews and Christians. However, its leaders made little headway in persuading the Egyptian population to adopt its religious beliefs.

The romanization of Arabic is the systematic rendering of written and spoken Arabic in the Latin script. Romanized Arabic is used for various purposes, among them transcription of names and titles, cataloging Arabic language works, language education when used instead of or alongside the Arabic script, and representation of the language in scientific publications by linguists. These formal systems, which often make use of diacritics and non-standard Latin characters, are used in academic settings for the benefit of non-speakers, contrasting with informal means of written communication used by speakers such as the Latin-based Arabic chat alphabet.

Different systems and strategies have been developed to address the inherent problems of rendering various Arabic varieties in the Latin script. Examples of such problems are the symbols for Arabic phonemes that do not exist in English or other European languages; the means of representing the Arabic definite article, which is always spelled the same way in written Arabic but has numerous pronunciations in the spoken language depending on context; and the representation of short vowels (usually i u or e o, accounting for variations such as Muslim and Moslem or Mohammed, Muhammad and Mohamed).

As part of the early Muslim conquests, which began under Muhammad in 622, the Rashidun Caliphate conquered the Sasanian Empire between 632 and 654. This event led to the decline of Zoroastrianism, which had been the official religion of Persia (or Iran) since the time of the Achaemenid Empire, circa 550 BC. The persecution of Zoroastrians by the early Muslims during and after this conflict prompted many of them to flee eastward to India, where they were taken as refugees by various kings.

While Arabia was witnessing the rise of Islam in the 7th century, Persia was struggling with unprecedented political, economic and social issues as well as military weakness; the Sasanian army had greatly exhausted itself in the Byzantine–Sasanian War of 602–628. Following the execution of Sasanian shah Khosrow II in 628, Persia's internal political stability began to deteriorate rapidly, leading to ten new royal claimants being enthroned within the next four years. Shortly afterwards, Persia was further devastated by the Sasanian Interregnum, a large-scale civil war that began in 628 and resulted in the government's decentralization by 632.
