On the authority of Abu Nadra who said

The Messenger of Allah ﷺ said on the middle day of the days of at-Tashreeq: “O people, verily your Lord is one and your father is one. Verily there is no superiority of an Arab over a non-Arab or of a non-Arab over an Arab, or of a red man over a black man, or of a black man over a red man, except in terms of taqwa (piety). Have I conveyed the message?” They said: The Messenger of Allah ﷺ has conveyed the message.
