That the Messenger of Allah (ﷺ) said: "Whoever arrogantly drags his garment, Allah will not look at him on the Day of Judgement." So Umm Salamah said: "What should the women do with their hems?" He said: "Slacken them a handspan." So she said: "Then their feet will be uncovered." He said: "Then slacken them a forearm's length and do not add to that."

He said: This Hadith is Hasan Sahih. In the Hadith there is a concession for women to drag their Izar because it covers them better.
