Sayyidah Aishah (may Allah be pleased with her) said: Sayyidah Sahlah bint Suhayl (may Allah be pleased with her) came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, I see signs of displeasure on the face of Abu Hudhayfah concerning the matter of Salim. The Prophet (peace and blessings be upon him) said: "Nurse him." She said: But he is grown up. The Messenger of Allah (peace and blessings be upon him) smiled and said: "Do I not know that he is a man?" (Sayyidah Aishah (may Allah be pleased with her)) said: So she did so, then came to him and said: By the One who honoured you with what He honoured you with, I have not (since) seen anything (of displeasure) on the face of Abu Hudhayfah.
