حَدَّثَنَا مُطَرِّفٌ أَبُو مُصْعَبٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ أَبِي الْمَوَالِي، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، قَالَ رَأَيْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يُصَلِّي فِي ثَوْبٍ وَاحِدٍ وَقَالَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يُصَلِّي فِي ثَوْبٍ.
Narrated Muhammad bin Al Munkadir: I saw Jabir bin `Abdullah praying in a single garment and he said that he had seen the Prophet (ﷺ) praying in a single garment.
