It was narrated that Abu Hurairah said:
"A man from Banu Fazdrah came to the Messenger of Allah, and said: 'O Messenger of Allah, 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 grey ones among them?' He said: 'Yes, there are some grey ones among them.' He said: 'Where does that come from?' He said: 'Perhaps it is hereditary.' He said: 'Likewise, perhaps this is hereditary! "
