"Sometimes an entire surah would be revealed to him, and sometimes separate ayat, so that he, peace be upon him, would join some of them to others until the surah became complete.
The first that was revealed to him of the Qur’an was the beginning of Surah al-Alaq,
then al-Muddaththir and al-Muzzammil. It has been said that the first to be revealed was al-Muddaththir, and it has been said the Fatihah of the Book. The former is the truth because of what has been narrated in the authentic hadith from A’ishah in the very long hadith on the beginning of the revelation in which she said: The angel came to him while he was in the cave of Hira, and said, “Recite!” He said, “I am not a reciter.” He said, “Then he took me and squeezed me until it distressed me, and then he released me and said, ‘Recite.’ I said, ‘I am not a reciter.’
Then he took me and squeezed me a second time until it distressed me, and then he released me and said, ‘Recite.’ I said, ‘I am not a reciter.’ Then he took me and squeezed me a third time until it distressed me, and then he released me and said, ‘Recite in the name of your Lord the One Who created. He created man from a blood clot. Recite and your Lord is the Most Generous the One Who taught man by the pen, taught man that which he did not know.’” The Messenger of Allah, may Allah bless him and grant him peace, returned with his heart in turmoil, and said, “Wrap me up.” So they wrapped him up until the fear he experienced left him".
