Prayer in a single Qamis

It was narrated that Salamah bin Al-Akwa said:

" I said: 'O Messenger of Allahﷺ, I go hunting wearing nothing but a single shirt. Can I pray in it?' He said: 'Fasten it to yourself even with a thorn.'"

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا الْعَطَّافُ، عَنْ مُوسَى بْنِ إِبْرَاهِيمَ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنِّي لأَكُونُ فِي الصَّيْدِ وَلَيْسَ عَلَىَّ إِلاَّ الْقَمِيصُ أَفَأُصَلِّي فِيهِ قَالَ " وَزُرَّهُ عَلَيْكَ وَلَوْ بِشَوْكَةٍ " .
