There came a person to the Prophet (may peace he upon him) ) from Banu Fazara and said: My wife has given birth to a child who is black, whereupon Allah's Apostle ﷺ said: Have you any camels? He said: Yes. He again said: What is this colour? He said: They are red. He said: Is there a dusky one among them? He said: Yes, there are dusky ones among them He said: How has it come about? He said: It is perhaps the strain to which it has reverted, whereupon he (the Holy Prophet) said: It is perhaps the strain to which he (the child) has reverted. (Using translation from Muslim 1500a)  

أَنَّ رَجُلًا مِنْ بَنِي فَزَارَةَ أَتَى رَسُولَ اللهِ ﷺ فَقَالَ إِنَّ امْرَأَتِي وَلَدَتْ غُلَامًا أَسْوَدَ فَقَالَ رَسُولُ اللهِ ﷺ «هَلْ لَكَ مِنْ إِبِلٍ؟» قَالَ نَعَمْ قَالَ «فَمَا أَلْوَانُهَا؟» قَالَ حُمْرٌ قَالَ «هَلْ فِيهَا مِنْ أَوْرَقَ؟» قَالَ إِنَّ فِيهَا لَوُرْقًا قَالَ «فَأَنَّى تَرَاهُ أَتَى ذَلِكَ؟» قَالَ عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ فَقَالَ رَسُولُ اللهِ ﷺ «وَهَذَا عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ»  

"A man from Banu Fazarah came to the Prophet and said: 'My wife has given birth to a black boy' -and he wanted to disown him. He said: 'Do you have camels?' He said: 'Yes.' He said: 'What color are they?' He said: 'Red.' He said: 'Are there any gray ones among them?' He said: 'There are some gray camels among them.' He said: 'Why is that do you think?' He said: 'Perhaps it is hereditary.' He said: 'Perhaps this is hereditary.' And he did not permit him to disown him." (Using translation from Nasāʾī 3479)  

جَاءَ رَجُلٌ مِنْ بَنِي فَزَارَةَ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ امْرَأَتِي وَلَدَتْ غُلَامًا أَسْوَدَ وَهُوَ يُرِيدُ الِانْتِفَاءَ مِنْهُ فَقَالَ «هَلْ لَكَ مِنْ إِبِلٍ؟» قَالَ نَعَمْ قَالَ «مَا أَلْوَانُهَا؟» قَالَ حُمْرٌ قَالَ «هَلْ فِيهَا مِنْ أَوْرَقَ؟» قَالَ فِيهَا ذَوْدٌ أَوْرَقُ قَالَ «فَمَا ذَاكَ تَرَى؟» قَالَ لَعَلَّهُ أَنْ يَكُونَ نَزَعَهَا عِرْقٌ قَالَ «فَلَعَلَّ هَذَا أَنْ يَكُونَ نَزَعَهُ عِرْقٌ» قَالَ فَلَمْ يُرَخِّصْ لَهُ فِي الِانْتِفَاءِ مِنْهُ  

"While we were with the Prophet, a man stood up and said: 'O Messenger of Allah, a black boy has been born to me.' The Messenger of Allah said: 'How did that happen?' He said: 'I do not know.' He said: 'Do you have camels?' He said: 'Yes.' He said: 'What color are they?' He said: 'Red.' He said: 'Are there any gray camels among them?' He said: 'There are some gray camels among them.' He said: 'Where do they come from?' He said: 'I do not know, O Messenger of Allah! Perhaps it is hereditary.' He said: 'Perhaps this is also hereditary.' Because of this, the Messenger of Allah decreed the following: 'It is not allowed for a man, to disown a child who was born on his bed, unless he claimed that he had seen an immoral act (Fahishah).'" (Using translation from Nasāʾī 3480)  

بَيْنَمَا نَحْنُ عِنْدَ رَسُولِ اللهِ ﷺ قَامَ رَجُلٌ فَقَالَ يَا رَسُولَ اللهِ إِنِّي وُلِدَ لِي غُلَامٌ أَسْوَدُ فَقَالَ النَّبِيُّ ﷺ «فَأَنَّى كَانَ ذَلِكَ؟» قَالَ مَا أَدْرِي قَالَ «فَهَلْ لَكَ مِنْ إِبِلٍ؟» قَالَ نَعَمْ قَالَ «فَمَا أَلْوَانُهَا؟» قَالَ حُمْرٌ قَالَ «فَهَلْ فِيهَا جَمَلٌ أَوْرَقُ؟» قَالَ فِيهَا إِبِلٌ وُرْقٌ قَالَ «فَأَنَّى كَانَ ذَلِكَ؟» قَالَ مَا أَدْرِي يَا رَسُولَ اللهِ إِلَّا أَنْ يَكُونَ نَزَعَهُ عِرْقٌ قَالَ «وَهَذَا لَعَلَّهُ نَزَعَهُ عِرْقٌ» فَمِنْ أَجْلِهِ «قَضَى رَسُولُ اللهِ ﷺ هَذَا لَا يَجُوزُ لِرَجُلٍ أَنْ يَنْتَفِيَ مِنْ وَلَدٍ وُلِدَ عَلَى فِرَاشِهِ إِلَّا أَنْ يَزْعُمَ أَنَّهُ رَأَى فَاحِشَةً»
