The revelation of the Qur'an began in the laila al-qadr of Ramadan (one of the odd nights after the 21st till end Ramadan) after the Prophet Muhammad had passed the fortieth year of his life (that is around the year 610), during his seclusion in the cave of Hira' on a mountain near Makka.

Bukharis Account [English translations of ahadith are, unless otherwise indicated, from Khan, Muhammad Muhsin: The Translation of the Meanings of Sahih al-Bukhari, 9 vols., Istanbul, 1978 (abbr. as Bukhari) and Siddiqui, Abdul Hamid: Sahih Muslim, 4 vols., Lahore, 1978 (abbr. as Muslim).]

This is the account, as reported in the Sahih of Bukhari:

Narrated Aisha the mother of the faithful believers: The commencement of the divine inspiration to Allah's apostle was in the form of good dreams which came like bright daylight (i.e. true) and then the love of seclusion was bestowed upon him.

He used to go in seclusion in the Cave of Hira', where he used to worship (Allah alone) continuously for many days before his desire to see his family. He used to take with him food for the stay and then come back to (his wife) Khadija to take his food likewise again, till suddenly the truth descended upon him while he was in the Cave of Hira'.

The angel came to him and asked him to read. The Prophet replied 'I do not know how to read'. The Prophet added, 'The angel caught me (forcibly) and pressed me so hard that I could not bear it any more. He then released me and again asked me to read and I replied, "I do not know how to read". Thereupon he caught me again and pressed me a second time till I could not bear it any more. He then released me and again asked me to read, but again I replied, "I do not know how to read" (or what shall I read?). Thereupon he caught me for the third time and pressed me, and then released me and said: "Read, in the name of Your Lord, who created, created man from a clot. Read! And Your Lord is the most bountiful" ... [Bukhari, I, No. 3; VI, No. 478; Muslim I, No. 301.]

The narration goes on to tell us that the Prophet went back to his wife Khadija and recounted to her his dreadful experience. She comforted him and both of them consulted Waraqa, Khadlja's relative and a learned Christian, about it. Waraqa told Muhammad that he had encountered the one 'whom Allah had sent to Moses' and that he would be driven out by his people

The Qur'an was sometimes revealed to respond to various events and incidents. Sometimes it was revealed to support the Prophet (saws) who was faced with many questions, whether by Muslims or non-Muslims, and hardships. Other times was revealed for legislation and for putting rules to govern the social, economical, and political life of Muslims.

The first verses to be revealed, according to the most correct opinion of scholars, are the first five verses of Surat Al-`Alaq, which happens to be Chapter 96 of the 114 chapters of the Qur'an.

Order of Verses

Muslim scholars agree that the order of the verses in every chapter was done or commanded by the Prophet (saws) himself following the commands of Almighty Allah.

The Prophet (saws) once told his Companions after he had received a certain revelation that the arch-angel Gabriel had specified for him the particular order of verses (Ahmad).

There are also many incidents narrated in the books of Sunnah regarding the Prophet's (saws) recitation during prayer. The Companions used to pray every day behind the Prophet (saws) and he used to recite the Qur'an in the order given to him by Allah, and they used to learn and memorize from his recitation.

There have never been any incident in which any of the Companions reciting in any order that violated the order of the verses showed to us by the Prophet (saws).

Order of Surahs

As for the order of the surahs (chapters), the most accepted view is that it was also applied following an instruction given by Almighty Allah. It has been recorded that the Prophet (saws) reviewed the Qur'an with the arch-angel Gabriel 24 times all within his life.

Every year, he used to review it once during the month of Ramadan with Gabriel. During the final year of the Prophet's life, Gabriel revised the Qur'an twice with the Prophet (saws) as a way of confirming it. The Prophet (saws), in turn, used to follow this order in teaching his Companions and communicating the message to them.
