"that a man from [Banu] Fazarah came to the Prophet ﷺ and said: 'O Messenger of Allah ﷺ! My wife gave birth to black boy." So the Prophet ﷺ said: "[Do you have any camels?]" He said: 'Yes." He said: "Then what are their colors?" He said: "Red." He said: "Is there a gray one among them?" He said: "Yes, there is a grey one among them." He said: "From where does that come?" He said: "Perhaps it is hereditary." He said: "Then in the same way, perhaps it is his heredity."  

جَاءَ رَجُلٌ مِنْ بَنِي فَزَارَةَ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ فَقَالَ النَّبِيُّ ﷺ هَلْ لَكَ مِنْ إِبِلٍ قَالَ نَعَمْ قَالَ فَمَا أَلْوَانُهَا قَالَ حُمْرٌ قَالَ فَهَلْ فِيهَا أَوْرَقُ قَالَ نَعَمْ إِنَّ فِيهَا لَوُرْقًا قَالَ أَنَّى أَتَاهَا ذَلِكَ قَالَ لَعَلَّ عِرْقًا نَزَعَهَا قَالَ فَهَذَا لَعَلَّ عِرْقًا نَزَعَهُ
