Al-Bukhârî reports according to Aishah, may Allah agree with her:
“The beginning of the divine inspiration (wahy) to the Messenger of Allah – may Allah’s Peace and blessings be upon him (pbuh)- were the truthful dreams during his sleep, every time he had a dream, it obviously realized, then He pbuh had an attraction for the solitary retreat.
Then, He pbuh went to Mount Hirâ where he devoted himself to the adoration during the nights and was preparing for these retreats, and then he returned to Khadijah’s house – May Allah be pleased with her- who helpt Him pbuh for another retreat until Truth surprised Him pbuh at Hirah.
“Then the angel appeared to Him saying: “Read” The Messenger of Allah pbuh said: “I answered him: I hardly read. Then he grabbed me and held me tight enough to exhaust me and then released me and said: Read! Then I replied: I do not read much. Then he squeezed me a second time to the point of exhausting me and then released me and said: Read! So I say: I do not read much. So he squeezed me a third time to the point of exhausting me and then released me and said, ‘Read in the name of your Lord who created‘ until ‘what he does not know.’ “
Then the Messenger of Allah pbuh returned to his wife Khadijah and cried, “Wrap to me! Wrap to me! “She hastened to keep Him wrapped until his terror was dispelled, then He said to Khadjah,” I feared for myself. “Khadijah told Him,” Allah forbids, Allah would not want you any harm. By Allah , you maintain your ties of kinship, you support the weak, you give to the poor, you welcome the hosts generously, and you help the victims of the real crises “.
Then she went with the Prophet pbuh to see her cousin Waraqah Ibn Nawfal. He was an old man, blind, endowed with a knowledge of the Old Books. Khadijah told him, “O my cousin, listen to your nephew’s words.” Then the Messenger of God, peace, and blessings of Allah be on him, told him what He saw. Waraqah said to him, “This Angel is the Confidant (Gabriel) whom Allah sent to Moses in the past, and please Allah that I am alive at the time your fellow citizens banish you!” – “They will banish me then?“, Exclaimed the Prophet, peace, and blessing of Allah be on him. “Yes,” said Waraqah, “never has a man brought what you bring without being persecuted, and if I live again that day, I will help you with all my strength.” Shortly after, Waraqah died, and the revelation was interrupted for a time.
