Islamic holy books in the context of "Dhikr"

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.

Sharia (/ʃəˈriːə/; Arabic: شَرِيعَة, romanized: sharīʿah, lit. 'path [to water]', IPA: [ʃaˈriːʕa]), also transliterated as Sharī'ah, Shari'a, or Shariah, is a body of religious law that form the Islamic tradition based on scriptures of Islam, particularly the Qur'an and hadith. In Islamic terminology sharīʿah refers to immutable, intangible divine law, in contrast to fiqh (Islamic jurisprudence), which refers to its interpretations by Islamic scholars. Sharia, or fiqh as traditionally known, has always been used alongside customary law from the very beginning in Islamic history; it has been elaborated and developed over the centuries by legal opinions issued by qualified jurists – reflecting the tendencies of different schools – and integrated with various economic, penal and administrative laws issued by Muslim rulers; and implemented for centuries by judges in the courts until recent times, when secularism was widely adopted in Islamic societies.

Traditional theory of Islamic jurisprudence recognizes four sources for al-sharia: the Qur'an, sunnah (or authentic ahadith), ijma (lit. consensus) (may be understood as ijma al-ummah (Arabic: إجماع الأمة) – a whole Islamic community consensus, or ijma al-aimmah (Arabic: إجماع الائـمـة) – a consensus by religious authorities), and analogical reasoning. It distinguishes two principal branches of law, rituals (Ibadah) and social dealings (Muamalat); subsections family law, relationships (commercial, political / administrative) and criminal law, in a wide range of topics assigning actions – capable of settling into different categories according to different understandings – to categories (ahkam) mainly as: mandatory, recommended, neutral, abhorred, and prohibited. Beyond legal norms, Sharia also enters many areas that are considered private practises today, such as belief, worshipping, ethics, clothing and lifestyle, and gives to those in command duties to intervene and regulate them.

The Quran (vocalized Arabic: الْقُرْآن‎, Quranic Arabic: الۡقُرۡءَان‎, al-Qurʾān [alqurˈʔaːn], lit. 'the recitation' or 'the lecture'), also romanized Qur'an or Koran, is the central religious text of Islam, believed by Muslims to be a revelation directly from God (Allāh). It is organized in 114 chapters (surah, pl. suwar) which consist of individual verses (āyah). Besides its religious significance, it is widely regarded as the finest work in Arabic literature, and has significantly influenced the Arabic language. It is the object of a modern field of academic research known as Quranic studies.

Muslims believe the Quran was orally revealed by God to the final Islamic prophet Muhammad through the angel Gabriel incrementally over a period of some 23 years, beginning on the Laylat al-Qadr, when Muhammad was 40, and concluding in 632, the year of his death. Muslims regard the Quran as Muhammad's most important miracle, a proof of his prophethood, and the culmination of a series of divine messages starting with those revealed to the first Islamic prophet Adam, including the holy books of the Torah, Psalms, and Gospel in Islam.

Muslims (Arabic: المسلمون, romanized: al-Muslimūn, lit. 'submitters [to God]') are people who adhere to Islam, a monotheistic religion belonging to the Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God of Abraham (or Allah) as it was revealed to Muhammad, the last Islamic prophet. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (Torah), the Zabur (Psalms), and the Injeel (Gospel). These earlier revelations are associated with Judaism and Christianity, which are regarded by Muslims as earlier versions of Islam. The majority of Muslims also follow the teachings and practices attributed to Muhammad (sunnah) as recorded in traditional accounts (hadith).

With an estimated population of almost 2 billion followers, Muslims comprise around 26% of the world's total population. In descending order, the percentage of people who identify as Muslims on each continental landmass stands at: 45% of Africa, 25% of Asia and Oceania collectively, 6% of Europe, and 1% of the Americas. Additionally, in subdivided geographical regions, the figure stands at: 91% of the Middle East–North Africa, 90% of Central Asia, 65% of the Caucasus, 42% of Southeast Asia, 32% of South Asia, and 42% of sub-Saharan Africa.

In Islam, Jesus (Arabic: عِيسَىٰ ٱبْنُ مَرْيَمَ‎, romanized: ʿĪsā ibn Maryam, lit. 'Jesus, son of Mary'), referred to by the Arabic rendering of his name Isa, is believed to be the penultimate prophet and messenger of God (Allāh) and the Messiah. He was the last of the messengers sent to the Israelites (Banī Isra'īl), and carried a revelation called the Injīl (Evangel or Gospel). In the Quran, Jesus is described as the Messiah (Arabic: المسيح, romanized: al-Masīḥ), born of a virgin, performing miracles, accompanied by his disciples, and rejected by the Jewish establishment; in contrast to the traditional Christian narrative, however, he is stated neither to have been crucified, nor executed, nor to have been resurrected. Rather, it is stated that it appeared to the Jews as if they had executed him and that they therefore say they killed Jesus, who had in truth ascended into Heaven. The Quran places Jesus among the greatest prophets and mentions him with various titles. The prophethood of Jesus is preceded by that of Yaḥyā ibn Zakariyyā (John the Baptist) and succeeded by Muhammad, the latter coming of whom Jesus is reported in the Quran to have foretold under the name Ahmad.

Most Christians view Jesus as God incarnate, the Son of God in human flesh, but the Quran denies the divinity of Jesus and his status as Son of God in several verses, and also says that Jesus did not claim to be personally God nor the Son of God. Islam teaches that Jesus' original message was altered (taḥrīf) after his being raised alive. The monotheism (tawḥīd) of Jesus is emphasized in the Quran. Like all prophets in Islam, Jesus is also called a Muslim (lit. submitter [to God]), as he preached that his followers should adopt the 'straight path' (Ṣirāṭ al-Mustaqīm). Jesus is attributed with a vast number of miracles in Islamic tradition.

In Islam, the Torah (Arabic: توراة‎, romanized: tawrat) is regarded as an Islamic holy book that was revealed by God to guide the Children of Israel. In the Quran, the word "Tawrat" appears eighteen times, particularly in passages mentioning the Jewish people or their history, including Jewish prophets who are also regarded as Islamic prophets and messengers, such as Moses. The Torah is held by Muslims in identification with other books of the Hebrew Bible and with Jewish writings and exegeses in the Talmud and Midrash.

Zabur (Arabic: ٱلزَّبُورِ, romanized: az-zabūr) is, according to Islam, the holy book of David, one of the holy books revealed by Allah before the Quran, alongside others such as the Tawrāh (Torah) and the Injīl (Gospel). Muslim tradition maintains that the Zabur mentioned in the Quran is the Psalms of Dawud (David in Islam).

The Christian monks and ascetics of pre-Islamic Arabia may be associated in pre-Islamic Arabic poetry with texts called mazmour, which in other contexts may refer to palm leaf documents. This has been interpreted by some as referring to psalters.
