Mishkat al-Masabih 4 Prayer كتاب الصلاة 188

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

Salama b. al-Akwa‘said that he told God’s Messenger he was a man who went out hunting, and asked whether he might pray in a single shirt. He replied, “Yes, but fasten it, even if it should be with a thorn.” Abu Dawud transmitted it and Nasa’i transmitted something similar.
