Sunan Abi Dawud, Hadith 632 ⓘ
Narrated Salamah ibn al-Akwa': I said: Messenger of Allah, I am a man who goes out hunting; may I pray in a single shirt? He replied: Yes, but fasten it even if it should be with a thorn.
حَدَّثَنَا الْقَعْنَبِيُّ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - عَنْ مُوسَى بْنِ إِبْرَاهِيمَ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنِّي رَجُلٌ أَصِيدُ أَفَأُصَلِّي فِي الْقَمِيصِ الْوَاحِدِ قَالَ " نَعَمْ وَازْرُرْهُ وَلَوْ بِشَوْكَةٍ " .
