Imām Bukhārī narrates: Yahyā ibn Bukair narrated to us, he said: Laith informed us, from 'Uqail, from Ibn Shihāb, he said: 'Urwah ibn al-Zubair informed me that 'Ā'ishah, may Allāh be pleased with her, informed him that:
the Muslim women used to be present with the Messenger of Allāh ﷺ for the Fajr prayer, wrapped in their cloaks. Then after praying, they would return to their houses, and no one could recognize them because of the darkness.
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، قَالَ أَخْبَرَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ عَائِشَةَ، أَخْبَرَتْهُ قَالَتْ، كُنَّ نِسَاءُ الْمُؤْمِنَاتِ يَشْهَدْنَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم صَلاَةَ الْفَجْرِ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ، ثُمَّ يَنْقَلِبْنَ إِلَى بُيُوتِهِنَّ حِينَ يَقْضِينَ الصَّلاَةَ، لاَ يَعْرِفُهُنَّ أَحَدٌ مِنَ الْغَلَسِ.
