It was narrated from Abu Hurairah that a man from Banu Fazarah came to the Messenger of Allah and said: My wife has given birth to a black boy. The Messenger of Allah said: Do you have camels? He said: Yes. He said: What color are they? He said: Red. He said: Are there any gray ones among them? He said: There are some gray ones among them. He said: Where do you think they come from? He said: Perhaps it is hereditary. He said: Likewise, perhaps this is hereditary.
