If The Qamis Is Tight, He Should Wrap It Around His Lower Body
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَوْ قَالَ قَالَ عُمَرُ رضى الله عنه " إِذَا كَانَ لأَحَدِكُمْ ثَوْبَانِ فَلْيُصَلِّ فِيهِمَا فَإِنْ لَمْ يَكُنْ إِلاَّ ثَوْبٌ وَاحِدٌ فَلْيَتَّزِرْ بِهِ وَلاَ يَشْتَمِلِ اشْتِمَالَ الْيَهُودِ " .
Ibn ‘Umar reported the Messenger of Allah (ﷺ) as saying, or reported ‘Umar as saying (the narrator is doubtful): if one of you has two (piece of) cloth, he should pray in them; if he has a single (piece of) cloth, he should use it as a wrapper, and should not hang it upon the shoulder like the Jews.
