Islam

Sufism (Arabic: الصوفية‎, romanized: aṣ-Ṣūfiyya or Arabic: التصوف‎, romanized: at-Taṣawwuf) is a mystic body of religious practice found within Islam which is characterized by a focus on Islamic purification, spirituality, ritualism, and asceticism.

Practitioners of Sufism are referred to as "Sufis" (from صُوفِيّ, ṣūfīy), and historically typically belonged to "orders" known as tariqa (pl. turuq) — congregations formed around a grand wali (saint) who would be the last in a chain of successive teachers linking back to Muhammad, with the goal of undergoing tazkiya (self purification) and the hope of reaching the spiritual station of ihsan. The ultimate aim of Sufis is to seek the pleasure of God by endeavoring to return to their original state of purity and natural disposition, known as fitra.

Shia Islam is the second-largest branch of Islam. It holds that Muhammad designated Ali ibn Abi Talib (r. 656–661) as both his political successor (caliph) and as the spiritual leader of the Muslim community (imam). However, his right is understood to have been usurped by a number of Muhammad's companions at the meeting of Saqifa, during which they appointed Abu Bakr (r. 632–634) as caliph instead. As such, Sunni Muslims believe Abu Bakr, Umar (r. 634–644), Uthman (r. 644–656) and Ali to be 'rightly-guided caliphs', whereas Shia Muslims regard only Ali as the legitimate successor.

Shia Muslims believe that the imamate continued through Ali's sons, Hasan and Husayn, after which various Shia branches developed and recognized different imams. They revere the ahl al-bayt, the family of Muhammad, maintaining that they possess divine knowledge. Shia holy sites include the shrine of Ali in Najaf, the shrine of Husayn in Karbala, and other mausoleums of the ahl al-bayt. Later events, such as Husayn's martyrdom in the Battle of Karbala (680 CE), further influenced the development of Shia Islam, contributing to the formation of a distinct religious sect with its own rituals and shared collective memory.

Sufi cosmology (Arabic: الكوزمولوجية الصوفية) is a Sufi approach to cosmology which discusses the creation of man and the universe, which according to mystics are the fundamental grounds upon which Islamic religious universe is based. According to Sufi cosmology, God's reason for the creation of this cosmos and humankind is the "manifestation" and "recognition" of Himself as it is stated in Hadith Qudsi – "I was a hidden Treasure; I desired to be recognized so I created the creature".

Ijtihad (/ˌɪdʒtəˈhɑːd/ IJ-tə-HAHD; Arabic: اجتهاد ijtihād [ʔidʒ.tihaːd], lit. 'physical effort' or 'mental effort') is an Islamic legal term referring to independent reasoning by an expert in Islamic law, or the thorough exertion of a jurist's mental faculty in finding a solution to a legal question. It is contrasted with taqlid (imitation, conformity to legal precedent). According to classical Sunni theory, ijtihad requires expertise in the Arabic language, theology, revealed texts, and principles of jurisprudence (usul al-fiqh), and is not employed where authentic and authoritative texts (Qur'an and hadith) are considered unambiguous with regard to the question, or where there is an existing scholarly consensus (ijma). Ijtihad is considered to be a religious duty for those qualified to perform it. An Islamic scholar who is qualified to perform ijtihad is called a "mujtahid".

For the first five centuries of Islam, the practice of ijtihad continued in theory and practice among Sunni Muslims. It then first became subject to dispute in the 12th century. By the 14th century, development of classic Islamic jurisprudence or fiqh prompted leading Sunni jurists to state that the main legal questions in Islam had been addressed, and to call for the scope of ijtihad to be restricted. In the modern era, this gave rise to a perception amongst Orientalist scholars and sections of the Muslim public that the so-called "gate of ijtihad" was closed at the start of the classical era. While recent scholarship established that the practice of Ijtihad had never ceased in Islamic history, the extent and mechanisms of legal change in the post-formative period remain a subject of debate. Differences amongst the Fuqaha (jurists) prevented Sunni Muslims from reaching any consensus (Ijma) on the issues of continuity of Ijtihad and existence of Mujtahids. Thus, Ijtihad remained a key aspect of Islamic jurisprudence throughout the centuries. Ijtihad was practiced throughout the Early modern period and claims for ijtihad and its superiority over taqlid were voiced unremittingly.

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.

In Islam, the ulama (US: /ˈuːləmɑː/ OO-lə-mah; also spelled ulema; Arabic: علماء, romanized: ʿulamāʾ, lit. 'the learned ones'; singular عالم, ʿālim; feminine singular عالمة, ʿālimah, plural عالمات, ʿālimāt) are scholars of Islamic doctrine and law. They are considered the guardians, transmitters, and interpreters of religious knowledge in Islam.

"Ulama" may refer broadly to the educated class of such religious scholars, including theologians, canon lawyers (muftis), judges (qadis), professors, and high state religious officials. Alternatively, "ulama" may refer specifically to those holding governmental positions in an Islamic state.

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 predominant legal schools: Hanafi, Maliki, Shafi'i and Hanbali.

Hadith studies is the academic study of hadith, a literature typically thought in Islamic religion to be a record of the words, actions, and the silent approval of the Muhammad as transmitted through chains of narrators.

A major area of interest in hadith studies has been the degree to which hadith can be used as a reliable source for reconstructing the biography of Muhammad, in parallel to the Islamic discipline of the hadith sciences. Since the pioneering work of Ignaz Goldziher, the sentiment has been that hadith are a more faithful source for understanding the religious, historical, and social developments in the first two centuries of Islam than they are a reliable record of Muhammad's life, especially concerning the formation of Islamic law, theology, and piety during the Umayyad and early Abbasid eras.

Ali ibn Abi Talib (Arabic: عَلِيُّ بْن أَبِي طَالِب, romanized: ʿAlī ibn Abī Ṭālib) (c. 600 – 661 CE) was the fourth Rashidun caliph who ruled from 656 CE until his assassination in 661, as well as the first Shia Imam. He was the cousin and son-in-law of the Islamic prophet Muhammad. Born to Abu Talib ibn Abd al-Muttalib and Fatima bint Asad, Ali was raised by his elder cousin Muhammad and was among the first to accept his teachings.

Ali played a pivotal role in the early years of Islam when Muslims were severely persecuted in Mecca. After the immigration (hijra) to Medina in 622, Muhammad gave his daughter Fatima to Ali in marriage and swore a pact of brotherhood with him. Ali served as Muhammad's secretary and deputy in this period, and was the flag bearer of his army. Numerous sayings of Muhammad praise Ali, the most controversial of which was uttered in 632 at the Ghadir Khumm, "Whoever I am his mawla, then Ali is his mawla." The interpretation of the polysemous Arabic word mawla is disputed: For Shia Muslims, Muhammad thus invested Ali with his religious and political authority, while Sunni Muslims view this as a mere statement of friendship and rapport. When Muhammad died in the same year, a group of Muslims met in the absence of Ali and appointed Abu Bakr (r. 632–634) as their leader. Ali later relinquished his claims to leadership and resigned from public life during the reigns of Abu Bakr and his successor, Umar (r. 634–644). Even though his advice was occasionally sought, the conflicts between Ali and the first two caliphs are epitomized by his refusal to follow their practices. This refusal cost Ali the caliphate to the benefit of Uthman (r. 644–656), who was thus appointed to succeed Umar by the electoral council. Ali was also highly critical of Uthman, who was widely accused of nepotism and corruption. Yet Ali also repeatedly mediated between the caliph and the provincial dissidents angered by his policies.
