Punishment of Disbelievers at War with Allah and His Apostle

Bukhari :: Book 8 :: Volume 82 :: Hadith 830

Narrated Abu Huraira:

A bedouin came to Allah's Apostle and said, "My wife has delivered a black child." The Prophet said to him, "Have you camels?" He replied, "Yes." The Prophet said, "What color are they?" He replied, "They are red." The Prophet further asked, "Are any of them gray in color?" He replied, "Yes." The Prophet asked him, "Whence did that grayness come?" He said, "I thing it descended from the camel's ancestors." Then the Prophet said (to him), "Therefore, this child of yours has most probably inherited the color from his ancestors."
