Abu Huraira (may Allah be pleased with him) narrates that a man came to the Messenger of Allah (peace and blessings be upon him) and said: "My wife has given birth to a black child." The Prophet asked: "Do you have camels?" He replied: "Yes!" The Prophet asked: "What is their color?" He said: "Red." The Prophet (peace be upon him) asked: "Are there any camels among them that are of a dusky color?" He replied: "There are several dusky-colored camels among them." The Prophet asked: "Where did they come from?" He said: "Perhaps some gene has pulled them." The Prophet (peace be upon him) said: "Perhaps this (child) has also been pulled by some gene."
