AL-QUR'AN

Islamic tradition relates that Muhammad received his first revelation in the Cave of Hira during one of his isolated retreats to the mountains. Thereafter, he received revelations over a period of twenty-three years. According to hadith and Muslim history, after Muhammad emigrated to Medina and formed an independent Muslim community, he ordered a considerable number of the sahabah to recite the Quran and to learn and teach the laws, which were revealed daily. Companions who engaged in the recitation of the Quran were called Qari. Since most sahabah were unable to read or write, they were ordered to learn from the prisoners-of-war the simple writing of the time. Thus a group of sahabah gradually became literate. As it was initially spoken, the Quran was recorded on tablets, bones and the wide, flat ends of date palm fronds. Most chapters were in use amongst early Muslims since they are mentioned in numerous sayings by both Sunni and Shia sources, relating Muhammad's use of the Quran as a call to Islam, the making of prayer and the manner of recitation. However, the Quran did not exist in book form at the time of Muhammad's death in 632.^[35][36]
Sahih Bukhari narrates Muhammad describing the revelations as, "Sometimes it is (revealed) like the ringing of a bell" and Aisha reported, "I saw the Prophet being inspired Divinely on a very cold day and noticed the sweat dropping from his forehead (as the Inspiration was over)".^[37] The Islamic studies scholar Welch states in the Encyclopaedia of Islam that he believes the graphic descriptions of Muhammad's condition at these moments may be regarded as genuine, because he was severely disturbed after these revelations. According to Welch, these seizures would have been seen by those around him as convincing evidence for the superhuman origin of Muhammad's inspirations. However, Muhammad's critics accused him of being a possessed man, a soothsayer or a magician since his experiences were similar to those claimed by such figures well known in ancient Arabia. Welch additionally states that it remains uncertain whether these experiences occurred before or after Muhammad's initial claim of prophethood.^[38]
The Quran states that Muhammad was ummi,^[39] interpreted as illiterate in Muslim tradition. According to Watt, the meaning of the Quranic term ummi is unscriptured rather than illiterate.

Compiling the Mus'haf

Quran manuscript from the 7th century CE, written on vellum in the Hijazi script.

According to Shias, Sufis and scarce Sunni scholars, Ali compiled a complete version of the Quran mus'haf^[1] immediately after Muhammad's death. The order of this mus'haf differed from that gathered later during Uthman's era. Despite this, Ali made no objection or resistance against standardized mus'haf, but kept his own book.^[35][40]
After seventy reciters were killed in the Battle of Yamama, the caliph Abu Bakr decided to collect the different chapters and verses into one volume. Thus, a group of reciters, including Zayd ibn Thabit, collected the chapters and verses and produced several hand-written copies of the complete book.^[35][41]

9th century Quran manuscript.

In about 650, as Islam expanded beyond the Arabian peninsula into Persia, the Levant and North Africa, the third caliph Uthman ibn Affan ordered the preparation of an official, standardized version, to preserve the sanctity of the text (and perhaps to keep the Rashidun Empire united, see Uthman Qur'an). Five reciters from amongst the companions produced a unique text from the first volume, which had been prepared on the orders of Abu Bakr and was kept with Hafsa bint Umar. The other copies already in the hands of Muslims in other areas were collected and sent to Medina where, on orders of the Caliph, they were destroyed by burning or boiling. This remains the authoritative text of the Quran to this day.^[35][42][43]
The Quran in its present form is generally considered by academic scholars to record the words spoken by Muhammad because the search for variants in Western academia has not yielded any differences of great significance. Historically, controversy over the Quran's content has rarely become an issue, although debates continue on th
