About Umm Salama, the wife of the Prophet Muhammad ﷺ , she said that the Prophet ﷺ was asked about the length of a woman's dress. He replied, "It should be a hand-span." So, I asked, "O Messenger of Allah, then will their feet be exposed?" He said, "No, it should hang below that." Abdullah Al-Nas said that people said this hadith was narrated by Nafi' from Sulaiman bin Yasar. – Weak Chain
