Abdullah ibn Barrad al-Ash'ari and Muhammad ibn al-'Ala' al-Hamdani narrated to us, both saying: Abu Usamah narrated to us from Burayd, from Abu Burda, from Abu Musa, who said: The Prophet, peace and blessings be upon him, was asked about things he disliked. When the questions became excessive, he became angry, then said to the people: "Ask me about whatever you wish." A man said: "Who is my father?" He said: "Your father is Hudhafa." Another man stood up and said: "Who is my father, O Messenger of Allah?" He said: "Your father is Salim, the freed slave of Shayba." When Umar saw the anger on the face of the Messenger of Allah, peace and blessings be upon him, he said: "O Messenger of Allah, we repent to Allah." In the narration of Abu Kurayb, he said: "Who is my father, O Messenger of Allah?" He said: "Your father is Salim, the freed slave of Shayba."
