Sahih Bukhari Volume 8, Book 86, Hadith 6849

حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم جَاءَهُ أَعْرَابِيٌّ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ‏.‏ فَقَالَ ‏"‏ هَلْ لَكَ مِنْ إِبِلٍ ‏"‏‏.‏ قَالَ نَعَمْ‏.‏ قَالَ ‏"‏ مَا أَلْوَانُهَا ‏"‏‏.‏ قَالَ حُمْرٌ‏.‏ قَالَ ‏"‏ فِيهَا مِنْ أَوْرَقَ ‏"‏‏.‏ قَالَ نَعَمْ‏.‏ قَالَ ‏"‏ فَأَنَّى كَانَ ذَلِكَ ‏"‏‏.‏ قَالَ أُرَاهُ عِرْقٌ نَزَعَهُ‏.‏ قَالَ ‏"‏ فَلَعَلَّ ابْنَكَ هَذَا نَزَعَهُ عِرْقٌ ‏"‏‏.‏

Narrated By 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 colour are they?" He replied, "They are red." The Prophet further asked, "Are any of them grey in colour?" He replied, "Yes." The Prophet asked him, "Whence did that greyness 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 colour from his ancestors."
