Narrated Muhammad bin Al-Munkadir: I went to Jabir bin `Abdullah and he was praying wrapped in a garment and his Rida was Lying beside him. When he finished the prayers, I said "O `Abdullah! You pray (in a single garment) while your Rida' is lying beside you." He replied, "Yes, I did it intentionally so that the ignorant ones like you might see me. I saw the Prophet (ﷺ) praying like this. "

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي ابْنُ أَبِي الْمَوَالِي، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، قَالَ دَخَلْتُ عَلَى جَابِرِ بْنِ عَبْدِ اللَّهِ وَهُوَ يُصَلِّي فِي ثَوْبٍ مُلْتَحِفًا بِهِ وَرِدَاؤُهُ مَوْضُوعٌ، فَلَمَّا انْصَرَفَ قُلْنَا يَا أَبَا عَبْدِ اللَّهِ تُصَلِّي وَرِدَاؤُكَ مَوْضُوعٌ قَالَ نَعَمْ، أَحْبَبْتُ أَنْ يَرَانِي الْجُهَّالُ مِثْلُكُمْ، رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يُصَلِّي هَكَذَا.
