Sunan an-Nasa'i, Volume 4, Book 26, Hadith 3319 (DarusSalam) ⓘ

It was narrated that 'Aishah said: "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.'"

أَخْبَرَنَا عَبْدُ الْجَبَّارِ بْنُ الْعَلاَءِ، عَنْ سُفْيَانَ، عَنِ الزُّهْرِيِّ، وَهِشَامِ بْنِ عُرْوَةَ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتِ اسْتَأْذَنَ عَلَىَّ عَمِّي أَفْلَحُ بَعْدَ مَا نَزَلَ الْحِجَابُ فَلَمْ آذَنْ لَهُ فَأَتَانِي النَّبِيُّ صلى الله عليه وسلم فَسَأَلْتُهُ فَقَالَ ‏"‏ ائْذَنِي لَهُ فَإِنَّهُ عَمُّكِ ‏"‏ ‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا أَرْضَعَتْنِي الْمَرْأَةُ وَلَمْ يُرْضِعْنِي الرَّجُلُ ‏.‏ قَالَ ‏"‏ ائْذَنِي لَهُ تَرِبَتْ يَمِينُكِ فَإِنَّهُ عَمُّكِ ‏"‏ ‏.‏
