وَعَنْهَا: { أَنْ أَفْلَحَ -أَخَا أَبِي الْقُعَيْسِ- جَاءَ يَسْتَأْذِنُ عَلَيْهَا بَعْدَ اَلْحِجَابِ. قَالَتْ: فَأَبَيْتُ أَنْ آذَنَ لَهُ, فَلَمَّا جَاءَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -أَخْبَرْتُهُ بِاَلَّذِي صَنَعْتُ, فَأَمَرَنِي أَنْ آذَنَ لَهُ عَلَيَّ. وَقَالَ:
"إِنَّهُ عَمُّكِ"
Narrated ['Aishah (RA)]:
Aflah (her foster suckling uncle), brother of Abul-Qais, came and asked her permission to enter after the Hijab (was instituted for women). She said, "I refused to allow him in and when Allah's Messenger (ﷺ) came, I told him about what I had done, so he commanded me to give him permission to enter where I am and said, 'He is your paternal uncle.'" [Agreed upon].
