Musnad Ahmad

It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that a man from 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 child of dark complexion." In fact, he wanted to present a request before the Prophet (peace and blessings be upon him) not to attribute the lineage of the child to himself. The Prophet (peace and blessings be upon him) asked him, "Do you have camels?" He said, "Yes." The Prophet (peace and blessings be upon him) asked, "What is their color?" He said, "Red." The Prophet (peace and blessings be upon him) asked, "Is there any gray-colored camel among them?" He said, "Yes, there is a gray-colored camel among them." The Prophet (peace and blessings be upon him) said, "How did the gray-colored camel come among the red camels?" He said, "Perhaps some vein has drawn this color." The Prophet (peace and blessings be upon him) said, "Then understand the same about this child, that perhaps some vein has drawn this color."
