"My wife has given birth to a black boy." The Messenger of Allah 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 ones among them." He said: "Where do you think they come from?" He said: "Perhaps it is hereditary." He said: "Likewise, perhaps this is hereditary."
أَنَّ رَجُلاً مِنْ بَنِي فَزَارَةَ أَتَى رَسُولَ اللَّهِ ﷺ فَقَالَ إِنَّ امْرَأَتِي وَلَدَتْ غُلاَمًا أَسْوَدَ فَقَالَ رَسُولُ اللَّهِ ﷺ 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 ﷺ وَهَذَا عَسَى أَنْ يَكُونَ نَزَعَهُ عِرْقٌ
