MID-CALF LOIN CLOTH H 809 "Ibn Omar was walking near the Prophet, praise and peace be upon him, and his loin cloth was long. He said to me, 'Abdullah, shorten your loin cloth.' So I tucked it up. He said, 'A little more.' So I tucked it up a little more and thereafter I always wore it higher. Someone from his tribe asked, 'How high?' He replied, 'To the mid-calf.'" R 809 Muslim with a chain up to ibn Omar who related that the Prophet, praise and peace be upon him, said this.
799- وعن ابن عمر رضي الله عنهما ، قَالَ : مررتُ عَلَى رسولِ الله صلى الله عليه وآله وسلم وفي إزَارِي استرخاءٌ ، فَقَالَ : "يَا عَبدَ اللهِ ، ارْفَعْ إزَارَكَ" فَرَفَعْتُهُ ثُمَّ قَالَ : "زِدْ" فَزِدْتُ ، فَمَا زِلْتُ أتَحَرَّاهَا بَعْدُ . فَقَالَ بَعْضُ القَوْم : إِلَى أينَ ؟ فَقَالَ : إِلَى أنْصَافِ السَّاقَيْنِ . رواه مسلم .
