"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 (ﷺ) 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.
