Narrated Umm Salamah, Ummul Mu'minin:

When the verse "That they should cast their outer garments over their persons" was revealed, the women of Ansar came out as if they had crows over their heads by wearing outer garments.

حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ ثَوْرٍ، عَنْ مَعْمَرٍ، عَنِ ابْنِ خُثَيْمٍ، عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ لَمَّا نَزَلَتْ ‏{‏ يُدْنِينَ عَلَيْهِنَّ مِنْ جَلاَبِيبِهِنَّ ‏}‏ خَرَجَ نِسَاءُ الأَنْصَارِ كَأَنَّ عَلَى رُءُوسِهِنَّ الْغِرْبَانُ مِنَ الأَكْسِيَةِ ‏.‏
