أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَجُلاً، مِنْ بَنِي فَزَارَةَ أَتَى رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " هَلْ لَكَ مِنْ إِبِلٍ " . قَالَ نَعَمْ . قَالَ " فَمَا أَلْوَانُهَا " . قَالَ حُمْرٌ . قَالَ " فَهَلْ فِيهَا مِنْ أَوْرَقَ " . قَالَ إِنَّ فِيهَا لَوُرْقًا . قَالَ " فَأَنَّى تَرَى أَتَى ذَلِكَ " . قَالَ عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " وَهَذَا عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ " .
Ishaq bin Ibrahim informed us; Sufyan reported to us, from al-Zuhri, from Sa'id bin al-Musayyib, from Abu Hurayrah: A man from Banu Fazara came to the Messenger of Allah and said, ‘My wife has given birth to a black boy.’ The Messenger of Allah asked, ‘Do you have camels?’ He said, ‘Yes.’ He asked, ‘What colors are they?’ He said, ‘Red.’ He asked, ‘Are there any gray ones among them?’ He said, ‘There are gray ones among them.’ He asked, ‘How do you think that came about?’ The man said, ‘Perhaps an ancestral trait brought it out.’ The Messenger of Allah said, ‘This one, too, may have inherited an ancestral trait.’
Translation notes
The source uses inherited coloring in camels as an analogy for a child's inherited traits.
