This tradition has also been transmitted through a different chain by ‘Amr b. Salamah. This version says:“I used to lead them in prayer with a sheet of cloth on me that was patched and torn. When I prostrated myself, my buttocks were disclosed.
حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا عَاصِمٌ الأَحْوَلُ، عَنْ عَمْرِو بْنِ سَلِمَةَ، بِهَذَا الْخَبَرِ قَالَ فَكُنْتُ أَؤُمُّهُمْ فِي بُرْدَةٍ مُوصَلَةٍ فِيهَا فَتْقٌ فَكُنْتُ إِذَا سَجَدْتُ خَرَجَتِ اسْتِي .
