عَن سَلمَة بن الْأَكْوَع قَالَ: قُلْتُ: يَا رَسُولَ اللَّهِ إِنِّي رَجُلٌ أَصِيدُ أَفَأُصَلِّي فِي الْقَمِيصِ الْوَاحِدِ؟ قَالَ: نَعَمْ وَازْرُرْهُ وَلَوْ بِشَوْكَةٍ ". رَوَاهُ أَبُو دَاوُدَ وَرَوَى النَّسَائِيّ نَحوه

Abu Huraira said that God’s Messenger forbade trailing garments during prayer and that a man should cover his mouth. Abu Dawud and Tirmidhi transmitted it.
