Sunan Ibn Majah Book 32, Hadith 3573

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، قَالَ قُلْتُ لأَبِي سَعِيدٍ هَلْ سَمِعْتَ مِنْ، رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ شَيْئًا فِي الإِزَارِ قَالَ نَعَمْ سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ ‏"‏ إِزْرَةُ الْمُؤْمِنِ إِلَى أَنْصَافِ سَاقَيْهِ لاَ جُنَاحَ عَلَيْهِ مَا بَيْنَهُ وَبَيْنَ الْكَعْبَيْنِ وَمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ فِي النَّارِ ‏"‏ ‏.‏ يَقُولُ ثَلاَثًا ‏"‏ لاَ يَنْظُرُ اللَّهُ إِلَى مَنْ جَرَّ إِزَارَهُ بَطَرًا ‏"‏ ‏.‏

It was narrated from ‘Ala bin ‘Abdur-Rahman that his father said:“I said to Abu Sa’eed: ‘Did you hear anything from the Messenger of Allah (ﷺ) concerning the lower wrap?’ He said: ‘Yes. I heard the Messenger of Allah (ﷺ) say: ‘The lower wrap of the believer should come to mid-calf, but there is no sin on him if it comes between that point and the ankle. But whatever is lower than the ankle is in the Fire.’ And he said three times: ‘Allah will not look at the one who lets his lower wrap drag out of vanity.’”
