My foster uncle came and asked permission (to enter) but I refused to admit him till I asked Allah's Apostle about that. He said, "He is your uncle, so allow him to come in." I said, "O Messenger of Allah ﷺ! I have been suckled by a woman and not by a man." Messenger of Allah ﷺ said, "He is your uncle, so let him enter upon you." And that happened after the order of Al-Hijab (compulsory veiling) was revealed. All things which become unlawful because of blood relations are unlawful because of the corresponding foster suckling relations.  

أَنَّهَا قَالَتْ جَاءَ عَمِّي مِنَ الرَّضَاعَةِ فَاسْتَأْذَنَ عَلَىَّ فَأَبَيْتُ أَنْ آذَنَ لَهُ حَتَّى أَسْأَلَ رَسُولَ اللَّهِ ﷺ فَجَاءَ رَسُولُ اللَّهِ ﷺ فَسَأَلْتُهُ عَنْ ذَلِكَ فَقَالَ إِنَّهُ عَمُّكِ فَأْذَنِي لَهُ قَالَتْ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَتْ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّهُ عَمُّكِ فَلْيَلِجْ عَلَيْكِ قَالَتْ عَائِشَةُ وَذَلِكَ بَعْدَ أَنْ ضُرِبَ عَلَيْنَا الْحِجَابُ قَالَتْ عَائِشَةُ يَحْرُمُ مِنَ الرَّضَاعَةِ مَا يَحْرُمُ مِنَ الْوِلاَدَةِ  

"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."  

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  

"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.'"  

قَالَتِ اسْتَأْذَنَ عَلَىَّ عَمِّي أَفْلَحُ بَعْدَ مَا نَزَلَ الْحِجَابُ فَلَمْ آذَنْ لَهُ فَأَتَانِي النَّبِيُّ ﷺ فَسَأَلْتُهُ فَقَالَ ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَ ائْذَنِي لَهُ تَرِبَتْ يَمِينُكِ فَإِنَّهُ عَمُّكِ  

“My uncle through suckling came and asked permission (to enter) but I refused to admit him until I asked the Messenger of Allah. So the Messenger of Allah said: “Let him in since he is your uncle.’” She said: “It is only the woman who suckled me; I was not suckled by the man.’ So he said: ‘Indeed he is your uncle, so let him in.’”  

جَاءَ عَمِّي مِنَ الرَّضَاعَةِ يَسْتَأْذِنُ عَلَىَّ فَأَبَيْتُ أَنْ آذَنَ لَهُ حَتَّى أَسْتَأْمِرَ رَسُولَ اللَّهِ ﷺ فَقَالَ رَسُولُ اللَّهِ ﷺ فَلْيَلِجْ عَلَيْكِ فَإِنَّهُ عَمُّكِ قَالَتْ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَ فَإِنَّهُ عَمُّكِ فَلْيَلِجْ عَلَيْكِ  

“My paternal uncle through breastfeeding, Aflah bin Abu Qu'ais, came and asked permission to visit me, after the ruling on veiling had been enjoined, and I refused to let him in, until the Prophet came in and said: 'He is your paternal uncle; let him in.' I said: 'But it is the woman who breastfed me; the man did not breastfeed me.' He said: 'May your hands be rubbed with dust', or: 'May your right hand be rubbed with dust!”  

أَنْ آذَنَ لَهُ حَتَّى دَخَلَ عَلَىَّ النَّبِيُّ ﷺ فَقَالَ إِنَّهُ عَمُّكِ فَأْذَنِي لَهُ فَقُلْتُ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَ تَرِبَتْ يَدَاكِ أَوْ يَمِينُكِ  

X“My paternal uncle through breastfeeding came to visit me and I refused to let him in. The Messenger of Allah said: 'Let your paternal uncle visit you.' I said: 'But it is the woman who breastfed me; the man did not breastfeed me.' He said: 'He is your paternal uncle; let him visit you.”

Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, umm al-muminin said, "My paternal uncle by suckling came to me and I refused to give him permission to enter until I had asked the Messenger of Allah ﷺ about it. The Messenger of Allah ﷺ came and I asked him about it. He said, 'He is your paternal uncle, so give him permission.' So I said, 'Messenger of Allah! The woman nursed me not the man.' He said, 'He is your paternal uncle, so let him enter.' " A'isha said, "That was after the veil had been imposed on us." A'isha added, "What is haram by birth is made haram by suckling."  

أَنْ آذَنَ لَهُ عَلَىَّ حَتَّى أَسْأَلَ رَسُولَ اللَّهِ ﷺ عَنْ ذَلِكَ فَجَاءَ رَسُولُ اللَّهِ ﷺ فَسَأَلْتُهُ عَنْ ذَلِكَ فَقَالَ إِنَّهُ عَمُّكِ فَأْذَنِي لَهُ قَالَتْ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ فَقَالَ إِنَّهُ عَمُّكِ فَلْيَلِجْ عَلَيْكِ قَالَتْ عَائِشَةُ وَذَلِكَ بَعْدَ مَا ضُرِبَ عَلَيْنَا الْحِجَابُ وَقَالَتْ عَائِشَةُ يَحْرُمُ مِنَ الرَّضَاعَةِ مَا يَحْرُمُ مِنَ الْوِلاَدَةِ

I said: 'But it is the woman who breastfed me; the man did not breastfeed me.' He said: 'May your hands be rubbed with dust', or: 'May your right hand be rubbed with dust!” (Using translation from Ibn Mājah 1948)   

أَنْ آذَنَ لَهُ فَدَخَلَ عَلَيَّ رَسُولُ اللهِ ﷺ فَقَالَ ائْذَنِي لَهُ فَإِنَّمَا هُوَ عَمُّكِ قُلْتُ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ قَالَ تَرِبَتْ يَمِينُكِ هُوَ عَمُّكِ

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»  

"عَنْ عَائِشَةَ قَالَتْ: جَاءَ أَفْلَح أَخُو أبِي القعيس يَسْتَأْذِنُ عَلَيْهَا فَقَالَ: إِنِّي عَمُّهَا فَأَبَتْ أنْ تَأْذَنَ لَهُ، فَلَمَّا دَخَلَ عَلَيْهَا النَّبِيُّ ﷺ ذَكَرَتْ ذَلِكَ لَهُ فَقَالَ: أَفَلَا أَذِنْتِ لِعَمِّكِ؟ قَالَتْ: يَا رَسُولَ اللهِ! إِنَّمَا أَرْضَعَتْنِي الْمَرَأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ، قَالَ: فأذني له فإنَّهُ عَمُّكِ تَرِبَتْ يَمِينُكِ، وَكَانَ أبو القعيس أَخَا زَوْجِ المَرْأَةِ الَّتِي أَرْضَعَتْ عَائِشَةَ".
