وَحَدَّثَنَاهُ قُتَيْبَةُ بْنُ سَعِيدٍ وَأَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ وَعَمْرٌو النَّاقِدُ وَزُهَيْرُ بْنُ حَرْبٍ - وَاللَّفْظُ لِقُتَيْبَةَ - قَالُوا حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنِ الزُّهْرِىِّ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ أَبِى هُرَيْرَةَ قَالَ جَاءَ رَجُلٌ مِنْ بَنِى فَزَارَةَ إِلَى النَّبِىِّ -صلى الله عليه وسلم- فَقَالَ إِنَّ امْرَأَتِى وَلَدَتْ غُلاَمًا أَسْوَدَ. فَقَالَ النَّبِىُّ -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 أَتَاهَا ذَلِكَ ». قَالَ عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ. قَالَ « وَهَذَا عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ ».

It was narrated that Abu Hurairah said: "A man from Banu Fazarah came to the Prophet (s.a.w) and said: 'My wife has given birth to a black boy.' The Prophet (s.a.w) said: 'Do you have camels?' He said: 'Yes.' He said: 'What are their colors?' He said: 'Red.' He said: 'Are there any dusky ones among them?' He said: 'There are dusky ones among them.' He said: 'Where does that come from?' He said: 'Perhaps it is an inherited trait.' He said: 'And perhaps this is an inherited trait.'"
