وَحَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ ، وَإِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ ، قَالاَ حَدَّثَنَا مَعْنٌ ، 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 . وَقَالَ الأَنْصَارِيُّ فِي رِوَايَتِهِ مُتَلَفِّفَاتٍ .
The Messenger of Allah (ﷺ) used to observe the morning prayer, and the women would go back wrapped in their mantles being unrecognisable because of the darkness before dawn. (Ishaq b. Musa) al-Ansari (one of the transmitters in this chain of narration) narrated" wrapped" (only) in his narration. (No mention was made of mantles.)
