Musnad Ahmad

It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that a man from Banu Fazarah came to the service of the Noble Prophet (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 Noble Prophet (peace and blessings be upon him) not to establish the lineage of the child himself. The Noble Prophet (peace and blessings be upon him) asked him, "Do you have camels?" He said, "Yes!" The Noble Prophet (peace and blessings be upon him) asked, "What is their color?" He said, "Red." The Noble Prophet (peace and blessings be upon him) asked, "Is there any camel among them of grayish color?" He said, "Yes, there is a grayish colored camel among them." The Noble Prophet (peace and blessings be upon him) said, "How did the grayish colored camel come among the red camels?" He said, "Perhaps some vein has drawn this color." The Noble Prophet (peace and blessings be upon him) said, "Then regarding this child, also understand that perhaps some vein has drawn this color."
