Ibn 'Umar reported:
حَدَّثَنِي أَبُو الطَّاهِرِ ، حَدَّثَنَا ابْنُ وَهْبٍ ، أَخْبَرَنِي عُمَرُ بْنُ مُحَمَّدٍ ، عَنْ عَبْدِ اللَّهِ بْنِ، وَاقِدٍ عَنِ ابْنِ عُمَرَ ، قَالَ مَرَرْتُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَفِي إِزَارِي اسْتِرْخَاءٌ فَقَالَ " يَا عَبْدَ اللَّهِ ارْفَعْ إِزَارَكَ " . فَرَفَعْتُهُ ثُمَّ قَالَ " زِدْ " . فَزِدْتُ فَمَا زِلْتُ أَتَحَرَّاهَا بَعْدُ . فَقَالَ بَعْضُ الْقَوْمِ إِلَى أَيْنَ فَقَالَ أَنْصَافِ السَّاقَيْنِ .
I happened to pass before Allah's Messenger (may peace be upon bin) with my lower garment trailing (upon the ground). He said: 'Abdullah, tug up your lower garment,, I tugged it up, and he again said: Tug it still further, and I tugged it still further and I went on tugging it afterward, whereupon some of the people said: To what extent? Thereupon he said: To the middle of the shanks.
