Arabic hadith text
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، قَالَ حَدَّثَنَا عَاصِمُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنِي وَاقِدُ بْنُ مُحَمَّدٍ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، قَالَ صَلَّى جَابِرٌ فِي إِزَارٍ قَدْ عَقَدَهُ مِنْ قِبَلِ قَفَاهُ، وَثِيَابُهُ مَوْضُوعَةٌ عَلَى الْمِشْجَبِ قَالَ لَهُ قَائِلٌ تُصَلِّي فِي إِزَارٍ وَاحِدٍ فَقَالَإِنَّمَا صَنَعْتُ ذَلِكَ لِيَرَانِي أَحْمَقُ مِثْلُكَ، وَأَيُّنَا كَانَ لَهُ ثَوْبَانِ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم
Translation
Narrated Muhammad bin Al-Munkadir
Once Jabir prayed with his Izar tied to his back while his clothes were Lying beside him on a wooden peg. Somebody asked him, "Do you offer your prayer in a single Izar?" He replied, "I did so to show it to a fool like you. Had anyone of us two garments in the lifetime of the Prophet?"
