Narrated Ibn 'Umar:

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.

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنْ جَرَّ ثَوْبَهُ خُيَلاَءَ لَمْ يَنْظُرِ اللَّهُ إِلَيْهِ يَوْمَ الْقِيَامَةِ " . فَقَالَتْ أُمُّ سَلَمَةَ فَكَيْفَ يَصْنَعْنَ النِّسَاءُ بِذُيُولِهِنَّ قَالَ " يُرْخِينَ شِبْرًا " . فَقَالَتْ إِذًا تَنْكَشِفَ أَقْدَامُهُنَّ . قَالَ " فَيُرْخِينَهُ ذِرَاعًا لاَ يَزِدْنَ عَلَيْهِ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
