Aflah, the brother of Abi Al-Quʿais, asked permission to visit me after the order of Al-Hijab was revealed. I said, "I will not permit him unless I take permission of the Prophet ﷺ about him for it was not the brother of Abi Al-Quʿais but the wife of Abi Al-Quʿais that nursed me." The Prophet ﷺ entered upon me, and I said to him, "O Messenger of Allah ﷺ! Aflah, the brother of Abi Al-Quʿais asked permission to visit me but I refused to permit him unless I took your permission." The Prophet ﷺ said, "What stopped you from permitting him? He is your uncle." I said, "O Messenger of Allah ﷺ! The man was not the person who had nursed me, but the woman, the wife of Abi Al-Quʿais had nursed me." He said, "Admit him, for he is your uncle. Taribat Yaminuki (may your right hand be saved)" ʿUrwa, the sub-narrator added: For that ʿAisha used to say, "Consider those things which are illegal because of blood relations as illegal because of the corresponding foster relations."  

قَالَتِ اسْتَأْذَنَ عَلَىَّ أَفْلَحُ أَخُو أَبِي الْقُعَيْسِ بَعْدَ مَا أُنْزِلَ الْحِجَابُ فَقُلْتُ لاَ آذَنُ لَهُ حَتَّى أَسْتَأْذِنَ فِيهِ النَّبِيَّ ﷺ فَإِنَّ أَخَاهُ أَبَا الْقُعَيْسِ لَيْسَ هُوَ أَرْضَعَنِي وَلَكِنْ أَرْضَعَتْنِي امْرَأَةُ أَبِي الْقُعَيْسِ فَدَخَلَ عَلَىَّ النَّبِيُّ ﷺ فَقُلْتُ لَهُ يَا رَسُولَ اللَّهِ إِنَّ أَفْلَحَ أَخَا أَبِي الْقُعَيْسِ اسْتَأْذَنَ فَأَبَيْتُ أَنْ آذَنَ حَتَّى أَسْتَأْذِنَكَ فَقَالَ النَّبِيُّ ﷺ وَمَا مَنَعَكِ أَنْ تَأْذَنِي عَمُّكِ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ الرَّجُلَ لَيْسَ هُوَ أَرْضَعَنِي وَلَكِنْ أَرْضَعَتْنِي امْرَأَةُ أَبِي الْقُعَيْسِ فَقَالَ ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ تَرِبَتْ يَمِينُكِ قَالَ عُرْوَةُ فَلِذَلِكَ كَانَتْ عَائِشَةُ تَقُولُ حَرِّمُوا مِنَ الرَّضَاعَةِ مَا تُحَرِّمُونَ مِنَ النَّسَبِ  

Aflah asked the permission to visit me but I did not allow him. He said, "Do you veil yourself before me although I am your uncle?" ʿAisha said, "How is that?" Aflah replied, "You were suckled by my brother's wife with my brother's milk." I asked Messenger of Allah ﷺ about it, and he said, "Aflah is right, so permit him to visit you."  

قَالَتِ اسْتَأْذَنَ عَلَىَّ أَفْلَحُ فَلَمْ آذَنْ لَهُ فَقَالَ أَتَحْتَجِبِينَ مِنِّي وَأَنَا عَمُّكِ فَقُلْتُ وَكَيْفَ ذَلِكَ قَالَ أَرْضَعَتْكِ امْرَأَةُ أَخِي بِلَبَنِ أَخِي فَقَالَتْ سَأَلْتُ عَنْ ذَلِكَ رَسُولَ اللَّهِ ﷺ فَقَالَ صَدَقَ أَفْلَحُ ائْذَنِي لَهُ
