"My paternal uncle Aflah asked permission to enter upon me after the (Verse of) Hijab had been revealed, but I did not let him in. The Prophet came to me and I asked him (about that) and he said: 'Let him in, for he is your paternal uncle.' I said: 'O Messenger of Allah, the woman breast-fed me, not the man.' He said: 'Let him in, may your hands be rubbed with dust, for he is your uncle.'" (Using translation from Nasāʾī 3317)  

اسْتَأْذَنَ عَلَيَّ عَمِّي أَفْلَحُ بَعْدَمَا نَزَلَ الْحِجَابُ فَلَمْ آذَنْ لَهُ فَأَتَى النَّبِيَّ ﷺ فَسَأَلَهُ فَقَالَ «ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ» قُلْتُ يَا رَسُولَ اللهِ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَ «ائْذَنِي لَهُ تَرِبَتْ يَمِينُكِ فَإِنَّهُ عَمُّكِ»  

[Machine] And Hisham said, "He is Abu Al-Quais." Then the Messenger of Allah ﷺ came and she informed him, and the Messenger of Allah ﷺ said, "Allow him."  

وَقَالَ هِشَامٌ هُوَ أَبُو الْقُعَيْسِ فَجَاءَ رَسُولُ اللهِ ﷺ فَأَخْبَرَتْهُ فَقَالَ رَسُولُ اللهِ ﷺ «ائْذَنِي لَهُ»  

(the wife of the Prophet) that while Messenger of Allah ﷺ was with her, she heard a voice of a man asking permission to enter the house of Hafsa. ʿAisha added: I said, "O Messenger of Allah ﷺ! This man is asking permission to enter your house." The Prophet ﷺ said, "I think he is so-and-so," naming the foster-uncle of Hafsa. ʿAisha said, "If so-and-so," naming her foster uncle, "were living, could he enter upon me?" The Prophet ﷺ said, "Yes, for foster suckling relations make all those things unlawful which are unlawful through corresponding birth (blood) relations." (Using translation from Bukhārī 5099)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ عِنْدَهَا وَأَنَّهَا سَمِعَتْ صَوْتَ رَجُلٍ يَسْتَأْذِنُ فِي بَيْتِ حَفْصَةَ فَقَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللهِ هَذَا رَجُلٌ يَسْتَأْذِنُ فِي بَيْتِكَ فَقَالَ رَسُولُ اللهِ ﷺ «أَرَاهُ فُلَانًا لِعَمِّ حَفْصَةَ مِنَ الرَّضَاعَةِ» قَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللهِ لَوْ كَانَ فُلَانٌ حَيًّا لِعَمِّهَا مِنَ الرَّضَاعَةِ دَخَلَ عَلَيَّ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ الرَّضَاعَةَ تُحَرِّمُ مَا تُحَرِّمُ الْوِلَادَةُ»  

"Let him in, for he is your paternal uncle." She said: "The woman breast-fed me, not the man." He said: "He is your paternal uncle, so let him visit you." (Using translation from Nasāʾī 3315)  

أَنَّ أَخَا أَبِي الْقُعَيْسِ اسْتَأْذَنَ عَلَى عَائِشَةَ بَعْدَ آيَةِ الْحِجَابِ فَأَبَتْ أَنْ تَأْذَنَ لَهُ فَذُكِرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ «ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ» فَقُلْتُ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ فَقَالَ «إِنَّهُ عَمُّكِ فَلْيَلِجْ عَلَيْكِ»  

"Aflah, the brother of Abu Al-Qu'ais, who was my paternal uncle through breast-feeding, used to ask permission to enter upon me, and I refused to let him in until the Messenger of Allah came, and I told him about that. He said: 'Let him in, for he is your paternal uncle.'" 'Aishah said: "That was after the (Verse of) Hijab had been revealed." (Using translation from Nasāʾī 3316)  

جَاءَ أَفْلَحُ أَخُو أَبِي الْقُعَيْسِ يَسْتَأْذِنُ عَلَيَّ وَهُوَ عَمِّي مِنَ الرَّضَاعَةِ فَأَبَيْتُ أَنْ آذَنَ لَهُ حَتَّى جَاءَ رَسُولُ اللهِ ﷺ فَأَخْبَرْتُهُ فَقَالَ «ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ» قَالَتْ عَائِشَةُ وَذَلِكَ بَعْدَ أَنْ نَزَلَ الْحِجَابُ  

"Aflah, the brother of Abu Al-Qu'ais, came and asked permission to enter, and I said: 'I will not let him in until I seek the permission of the Prophet of Allah.' When the Prophet of Allah came, I said to him: 'Aflah, the brother of Abu Al-Qu'ais, came and asked permission to enter, but I refused to let him in.' He said: 'Let him in, for he is your paternal uncle.' I said: 'The wife of Abu Al-Qu'ais breast-fed me; the man did not breast-feed me.' He said: 'Let him in, for he is your paternal uncle.'" (Using translation from Nasāʾī 3318)  

جَاءَ أَفْلَحُ أَخُو أَبِي الْقُعَيْسِ يَسْتَأْذِنُ فَقُلْتُ لَا آذَنُ لَهُ حَتَّى أَسْتَأْذِنَ نَبِيَّ اللهِ ﷺ فَلَمَّا جَاءَ نَبِيُّ اللهِ ﷺ قُلْتُ لَهُ جَاءَ أَفْلَحُ أَخُو أَبِي الْقُعَيْسِ يَسْتَأْذِنُ فَأَبَيْتُ أَنْ آذَنَ لَهُ فَقَالَ «ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ» قُلْتُ إِنَّمَا أَرْضَعَتْنِي امْرَأَةُ أَبِي الْقُعَيْسِ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَ «ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ»
