Sunan an-Nasa'i, Book 6, Hadith 550 (In-Book) ⓘ
It was narrated that 'Aishah said: "When the Messenger of Allah has prayed Subh, the women would depart, wrapped in their wrappers, unrecognizable because of the darkness."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، قَالَتْ إِنْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيُصَلِّي الصُّبْحَ فَيَنْصَرِفُ النِّسَاءُ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ مَا يُعْرَفْنَ مِنَ الْغَلَسِ .
