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?" (Using translation from Bukhārī 352)   

صَلَّى جَابِرٌ فِي إِزَارٍ قَدْ عَقَدَهُ مِنْ قِبَلِ قَفَاهُ وَثِيَابُهُ مَوْضُوعَةٌ عَلَى الْمِشْجَبِ فَقَالَ لَهُ قَائِلٌ أَتُصَلِّي فِي ثَوْبٍ وَاحِدٍ؟ قَالَ أَمَا إِنِّي إِنَّمَا صَنَعْتُ ذَلِكَ لِيَرَانِي أَحْمَقُ مِثْلُكَ وَأَيُّنَا كَانَ لَهُ ثَوْبَانِ فِي عَهْدِ رَسُولِ اللهِ ﷺ
