The Qur'an is divided into 114 suras, or chapters, which combined, contain 6,236 ayat, or verses. The chronologically earlier suras, revealed at Mecca, are primarily concerned with ethical and spiritual topics. The later Medinan suras mostly discuss social and moral issues relevant to the Muslim community.[33] The Qur'an is more concerned with moral guidance than legal instruction, and is considered the "sourcebook of Islamic principles and values".[34] Muslim jurists consult the hadith, or the written record of Muhammad's life, to both supplement the Qur'an and assist with its interpretation. The science of Qur'anic commentary and exegesis is known as tafsir.[35]
The word Qur'an means "recitation". When Muslims speak in the abstract about "the Qur'an", they usually mean the scripture as recited in Arabic rather than the printed work or any translation of it. To Muslims, the Qur'an is perfect only as revealed in the original Arabic; translations are necessarily deficient because of language differences, the fallibility of translators, and the impossibility of preserving the original's inspired style. Translations are therefore regarded only as commentaries on the Qur'an, or "interpretations of its meaning", not as the Qur'an itself.[36]
Angels:
Belief in angels is crucial to the faith of Islam. The Arabic word for angel (malak) means "messenger", like its counterparts in Hebrew (malakh) and Greek (angelos). According to the Qur'an, angels do not possess free will, and worship God in perfect obedience.[37] Angels' duties include communicating revelations from God, glorifying God, recording every person's actions, and taking a person's soul at the time of death. They are also thought to intercede on man's behalf. The Qur'an describes angels as "messengers with wings ? two, or three, or four (pairs): He [God] adds to Creation as He pleases?"[38]
Muhammad:
Muhammad[39] (c. 570 ? June 8, 632) was an Arab religious, political, and military leader who founded the religion of Islam as a historical phenomenon. Muslims view him not as the creator of a new religion, but as the restorer of the original, uncorrupted monotheistic faith of Adam, Abraham and others. In Muslim tradition, Muhammad is viewed as the last and the greatest in a series of prophets ? as the man closest to perfection, the possessor of all virtues.[40] For the last 23 years of his life, beginning at age 40, Muhammad reported receiving revelations from God. The content of these revelations, known as the Qur'an, was memorized and recorded by his companions.[41]
During this time, Muhammad preached to the people of Mecca, imploring them to abandon polytheism. Although some converted to Islam, Muhammad and his followers were persecuted by the leading Meccan authorities. After 13 years of preaching, Muhammad and the Muslims performed the Hijra ("emigration") to the city of Medina (formerly known as Yathrib) in 622. There, with the Medinan converts (Ansar) and the Meccan migrants (Muhajirun), Muhammad established his political and religious authority. Within years, two battles had been fought against Meccan forces: the Battle of Badr in 624, which was a Muslim victory, and the Battle of Uhud in 625, which ended inconclusively. Conflict with Medinan Jewish clans who opposed the Muslims led to their exile, enslavement or death, and the Jewish enclave of Khaybar was subdued. At the same time, Meccan trade routes were cut off as Muhammad brought surrounding desert tribes under his control.[42] By 629 Muhammad was victorious in the nearly bloodless Conquest of Mecca, and by the time of his death in 632 he ruled over the Arabian peninsula.[43]
In Islam, the "normative" example of Muhammad's life is called the Sunnah (literally "trodden path"). This example is preserved in traditions known as hadith ("reports"), which recount his words, his actions, and his personal characteristics. The classical Muslim jurist ash-Shafi'i (d. 820) emphasized the importance of the Sunnah in Islamic law, and Muslims are encouraged to emulate Muhammad's actions in their daily lives. The Sunnah is seen as crucial to guiding interpretation of the Qur'an.[44]
