Abu Huraira (Allah be pleased with him) reported: A desert Arab came to Messenger of Allah ﷺ and said: My wife has given birth to a dark-complexioned child and I have disowned him. Thereupon Allah's Apostle ﷺ said: Have you any camels? He said: Yes. He said: What is their colour? He said? They are red. He said: Is there anyone dusky among them? He said: Yes. Messenger of Allah ﷺ said: How has it come about? He said: Messenger of Allah, it is perhaps due to the strain to which it has reverted, whereupon Prophet ﷺ said: It (the birth) of the black child may be due to the strain to which he (the child) might have reverted.

وَحَدَّثَنِي أَبُو الطَّاهِرِ، وَحَرْمَلَةُ بْنُ يَحْيَى، - وَاللَّفْظُ لِحَرْمَلَةَ - قَالاَ أَخْبَرَنَا ابْنُ، وَهْبٍ أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ وَإِنِّي أَنْكَرْتُهُ . فَقَالَ لَهُ النَّبِيُّ ﷺ " هَلْ لَكَ مِنْ إِبِلٍ " . قَالَ نَعَمْ . قَالَ " مَا أَلْوَانُهَا " . قَالَ حُمْرٌ . قَالَ " فَهَلْ فِيهَا مِنْ أَوْرَقَ " . قَالَ نَعَمْ . قَالَ رَسُولُ اللَّهِ ﷺ " فَأَنَّى هُوَ " . قَالَ لَعَلَّهُ يَا رَسُولَ اللَّهِ يَكُونُ نَزَعَهُ عِرْقٌ لَهُ . فَقَالَ لَهُ النَّبِيُّ ﷺ " وَهَذَا لَعَلَّهُ يَكُونُ نَزَعَهُ عِرْقٌ لَهُ " .
