Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: A man from the tribe of Banu Fazarah came to the service of the Prophet Muhammad (peace be upon him) and said: My wife has given birth to a black child. The Prophet Muhammad (peace be upon him) asked: Do you have camels? He replied: Yes. The Prophet (peace be upon him) asked: What is their color? He replied: Red. The Prophet (peace be upon him) asked: Is there any gray among them? He replied: There is one gray among them. The Prophet (peace be upon him) asked: Where did that come from? He replied: Some vein must have pulled it. The Prophet (peace be upon him) said: Then perhaps some vein has pulled this one too.
