May Allah have mercy on the early immigrant women. When the verse "That they should draw their veils over their bosoms" was revealed, they tore their thick outer garments and made veils from them.
أَنَّهَا قَالَتْ يَرْحَمُ اللَّهُ نِسَاءَ الْمُهَاجِرَاتِ الأُوَلَ لَمَّا أَنْزَلَ اللَّهُ { وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ } شَقَقْنَ أَكْنَفَ قَالَ ابْنُ صَالِحٍ أَكْثَفَ مُرُوطِهِنَّ فَاخْتَمَرْنَ بِهَا
May Allah bestow His Mercy on the early emigrant women. When Allah revealed: "... and to draw their veils all over their Juyubihinna (i.e., their bodies, faces, necks and bosoms)..." (V.24:31) they tore their Murat (woolen dresses or waist-binding clothes or aprons etc.) and covered their heads and faces with those torn Muruts.
يَرْحَمُ اللَّهُ نِسَاءَ الْمُهَاجِرَاتِ الأُوَلَ لَمَّا أَنْزَلَ اللَّهُ {وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ} شَقَّقْنَ مُرُوطَهُنَّ فَاخْتَمَرْنَ بِها
May Allah have mercy on the early immigrant women. When the verse "That they should draw their veils over their bosoms" was revealed, they tore their thick outer garments and made veils from them. (Using translation from Abū Dāʾūd 4102)
يَرْحَمُ اللهُ نِسَاءَ الْمُهَاجِرَاتِ الْأُوَلِ لَمَّا أَنْزَلَ اللهُ تَعَالَى {وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ} [النور 31] شَقَقْنَ أَكْنَفَ قَالَ ابْنُ صَالِحٍ أَكْثَفَ مُرُوطِهِنَّ فَاخْتَمَرْنَ بِهَا
