that a man from [Banu] Fazarah came to the Prophet (ﷺ) and said: 'O Messenger of Allah (ﷺ)! My wife gave birth to black boy. So the Prophet (s.a.w) said: [Do you have any camels?] He said: 'Yes. He said: Then what are their colors? He said: Red. He said: Is there a gray one among them? He said: Yes, there is a grey one among them. He said: From where does that come? He said: Perhaps it is hereditary. He said: Then in the same way, perhaps it is his heredity.

[Abu 'Eisa said:] This Hadith is Hasan Sahih.
