Mishkat al-Masabih #4153

When God’s messenger mentioned the lower garment Umm Salama 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, Nasa’i and Ibn Majah transmitted it. 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.
