Sahih al-Bukhari 7314
Narrated Abu Huraira:
A bedouin came to Allah's Messenger (ﷺ) and said, "My wife has delivered a black boy, and I suspect that he 
is not my child." Allah's Messenger (ﷺ) said to him, "Have you got camels?" The bedouin said, "Yes." The 
Prophet said, "What color are they?" The bedouin said, "They are red." The Prophet (ﷺ) said, "Are any of 
them Grey?" He said, "There are Grey ones among them." The Prophet (ﷺ) said, "Whence do you think 
this color came to them?" The bedouin said, "O Allah's Messenger (ﷺ)! It resulted from hereditary 
disposition." The Prophet (ﷺ) said, "And this (i.e., your child) has inherited his color from his ancestors." 
The Prophet (ﷺ) did not allow him to deny his paternity of the child.
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.‏
