Riyad as-Salihin 800
Ibn 'Umar (May Allah be pleased with them) reported:
The Messenger of Allah (ﷺ) said, "On the Day of Resurrection, Allah will not look at the one who trails his lower garment out of arrogance." Umm Salamah (May Allah be pleased with her) asked: "What should women do with the hem of their clothes?" He (ﷺ) said, "They might lower them a hand's span." She said: "But their feet would still remain exposed." He said, "Let them lower them equal to arm's length but not more than that." [Abu Dawud and At-Tirmidhi] .
وعنه قال‏:‏ قال رسول الله صلى الله عليه وسلم‏:‏ من جر ثوبه خيلاء لم ينظر الله إليه يوم القيامة‏"‏ فقالت أم سلمة‏:‏ فكيف تصنع النساء بذيولهن، قال‏:‏ ‏"‏يرخين شبراً‏"‏ قالت‏:‏ ِإذاً تنكشف أقدامهن‏.‏ قال‏:‏ ‏"‏فيرخينه ذراعاً لا يزدن‏"‏‏.((رواه أبو داود والترمذي))
