How the Qur'an Was Revealed and Compiled
Section 7 of 28 · Foundations of Islam · Hamza Yusuf
The First to Believe
During this time, he began to tell people who were close to him. And Khadījah is the first person who believes him — his wife, which is interesting. She did not abandon him. She was right there, and she said: I believe this. His cousin, the son of his uncle, who was living in his house and whom he was taking care of, and who was a young boy at that time, also says that he believes; he tells him that he believes, in the tradition. And then other people, from among the very close people that knew him: Abū Bakr al-Ṣiddīq was a very close person.
But at a certain point he is commanded to warn his family. So he gathers them all together, and he says to them: what would you say if I told you that there was an army on the other side of the mountains of Mecca waiting to attack you? And they said: we would believe you, because you are al-Amīn, you are the trustworthy one. And he said: what would you say if I were a messenger of God, and I was sent to you? And they said: we do not believe you. And they rejected that.
