Hadith 4335
وَفِي رِوَايَةِ التِّرْمِذِيِّ وَالنَّسَائِيِّ عَنِ ابْنِ عُمَرَ فَقَالَتْ: إِذًا تَنْكَشِفُ أَقْدَامُهُنَّ قَالَ: «فَيُرْخِينَ ذِرَاعًا لَا يزدن عَلَيْهِ»
In the version of Tirmidhi and Nasa’i 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.
