It was narrated that ‘Amr bin Dinar said:
“When Ibn ‘Abbas was in Basrah, he performed prayer on his rug, then he told his companions that the Messenger of Allah ﷺ used to perform prayer on his rug.”

حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، حَدَّثَنِي زَمْعَةُ بْنُ صَالِحٍ، عَنْ عَمْرِو بْنِ دِينَارٍ، قَالَ صَلَّى ابْنُ عَبَّاسٍ وَهُوَ بِالْبَصْرَةِ عَلَى بِسَاطِهِ ثُمَّ حَدَّثَ أَصْحَابَهُ، أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي عَلَى بِسَاطِهِ .
