Abu Sa'id al-Khudri said, “I visited the Prophet and saw him praying on a reed mat on which he was prostrating himself.” He said, “And I saw him praying in a single garment with part over his shoulder.” Muslim transmitted it.
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
