Abu Musa:
The Prophet (ﷺ) was asked about things which he did not like, but when the questioners insisted, the
Prophet got angry. He then said to the people, "Ask me anything you like." A man asked, "Who is my
father?" The Prophet (ﷺ) replied, "Your father is Hudhafa." Then another man got up and said, "Who is
my father, O Allah's Messenger (ﷺ) ?" He replied, "Your father is Salim, Maula (the freed slave) of Shaiba."
So when `Umar saw that (the anger) on the face of the Prophet (ﷺ) he said, "O Allah's Messenger (ﷺ)! We repent
to Allah (Our offending you).
