CORRECT LENGTH OF A LOIN CLOTH H 808 "The loin cloth of a Muslim should be to the mid-calf, but there is no harm if it is above the ankles. That which hangs below the ankles is in the Fire. Allah will not look at one who lengthens his loin cloth through pride." R 808 Abu Daud with a chain up to Abu Sa'id Khudri who related that the Prophet, praise and peace be upon him, said this.
798- وعن أَبي سعيد الخدريِّ رضي الله عنه ، قَالَ : قَالَ رسولُ الله صلى الله عليه وآله وسلم : "إزْرَةُ المُسْلِمِ إِلَى نِصْفِ السَّاقِ ، وَلاَ حَرَجَ - أَوْ لاَ جُنَاحَ - فِيمَا بَيْنَهُ وَبَيْنَ الكَعْبَيْنِ ، فمَا كَانَ أسْفَلَ مِنَ الكَعْبَيْنِ فَهُوَ في النَّارِ ، وَمَنْ جَرَّ إزَارَهُ بَطَراً لَمْ يَنْظُرِ اللهُ إِلَيْهِ" رواه أَبُو داود بإسنادٍ صحيحٍ .
