Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: A Bedouin from the tribe of Banu Fazarah came to the service of the Prophet Muhammad (peace and blessings be upon him) and said: O Messenger of Allah! My wife has given birth to a black child. The Prophet (peace and blessings be upon him) asked:“Do you have camels?”He replied: Yes. The Prophet (peace and blessings be upon him) asked:“What is their color?”He replied: Red. The Prophet (peace and blessings be upon him) asked:“Is there any gray among them?”He replied: There is one gray among them. The Prophet (peace and blessings be upon him) asked:“Where did that come from?”He replied: Perhaps some gene pulled it out. So the Prophet (peace and blessings be upon him) said:“Perhaps some gene has pulled this one out as well.”
