عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: دَخَلْتُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَرَأَيْتُهُ يُصَلِّي عَلَى حَصِيرٍ يَسْجُدُ عَلَيْهِ. قَالَ: وَرَأَيْتُهُ يُصَلِّي فِي ثَوْبٍ وَاحِدٍ مُتَوَشِّحًا بِهِ. رَوَاهُ مُسْلِمٌ

‘Amr b. Shu'aib, on his father's authority, said that his grandfather declared he had seen God’s Messenger praying both barefoot and wearing sandals. Abu Dawud transmitted it.
