وَعَن أم سَلمَة
قَالَتْ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِينَ ذَكَرَ الْإِزَارَ: فَالْمَرْأَةُ يَا رَسُولَ اللَّهِ؟ قَالَ: «تُرْخِي شِبْرًا» فَقَالَتْ: إِذًا تَنْكَشِفُ عَنْهَا قَالَ: «فَذِرَاعًا لَا تَزِيدُ عَلَيْهِ» وَفِي رِوَايَةِ التِّرْمِذِيِّ وَالنَّسَائِيِّ عَنِ ابْنِ عُمَرَ فَقَالَتْ: إِذًا تَنْكَشِفُ أَقْدَامُهُنَّ قَالَ: «فَيُرْخِينَ ذِرَاعًا لَا يزدن عَلَيْهِ»
When God’s messenger mentioned the lower garment Umm Salamah asked what a woman should do and he said she should let it down a span. She replied that in that case she would not be completely covered, and he said she might let it down a cubit, but no more. Malik, Abu Dawud, Nasai and Ibn Majah transmitted it. In the version of Tirmidhi and Nasai on the authority of Ibn Umar she said their feet would then be uncovered, and he replied that they should let it down a cubit, but no more.
