Musnad Ahmad

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