Sahih al-Bukhari 4980

Musa ibn Ismail related to us; Mutamir related to us, saying: I heard my father, from Abu Uthman, who said: I was informed that Gabriel came to the Prophet (peace and blessings be upon him) while Umm Salama was with him, and he began speaking. The Prophet said to Umm Salama, ‘Who is this?’—or words to that effect. She said, ‘This is Dihya.’ When he got up and left, she said, ‘By Allah, I thought he was none other than him until I heard the Prophet’s sermon, in which he told the story of Gabriel’—or words to that effect. My father said: I asked Abu Uthman, ‘From whom did you hear this?’ He said, ‘From Usama ibn Zayd.’
