Sahih Bukhari Volume 9, Book 96, Hadith 7316

حَدَّثَنَا أَصْبَغُ بْنُ الْفَرَجِ، حَدَّثَنِي ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ أَعْرَابِيًّا، أَتَى رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ، وَإِنِّي أَنْكَرْتُهُ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ هَلْ لَكَ مِنْ إِبِلٍ ‏"‏‏.‏ قَالَ نَعَمْ‏.‏ قَالَ ‏"‏ فَمَا أَلْوَانُهَا ‏"‏‏.‏ قَالَ حُمْرٌ‏.‏ قَالَ ‏"‏ هَلْ فِيهَا مِنْ أَوْرَقَ ‏"‏‏.‏ قَالَ إِنَّ فِيهَا لَوُرْقًا‏.‏ قَالَ ‏"‏ فَأَنَّى تُرَى ذَلِكَ جَاءَهَا ‏"‏‏.‏ قَالَ يَا رَسُولَ اللَّهِ عِرْقٌ نَزَعَهَا‏.‏ قَالَ ‏"‏ وَلَعَلَّ هَذَا عِرْقٌ نَزَعَهُ ‏"‏‏.‏ وَلَمْ يُرَخِّصْ لَهُ فِي الاِنْتِفَاءِ مِنْهُ

Narrated By Abu Huraira : A bedouin came to Allah's Apostle and said, "My wife has delivered a black boy, and I suspect that he is not my child." Allah's Apostle said to him, "Have you got camels?" The bedouin said, "Yes." The Prophet said, "What colour are they?" The bedouin said, "They are red." The Prophet said, "Are any of them Grey?" He said, "There are Grey ones among them." The Prophet said, "Whence do you think this colour came to them?" The bedouin said, "O Allah's Apostle! It resulted from hereditary disposition." The Prophet said, "And this (i.e., your child) has inherited his colour from his ancestors." The Prophet did not allow him to deny his paternity of the child.
