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 garments, let him pray in them; and if he has only one garment, let him tie it around his waist as an izar, and not wrap himself in it in the manner of the Jews.
