مُوَطَّأُ مَالِكٍ
Muwatta Malik 324
Prayer in Congregation
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ مَنْ لَمْ يَجِدْ ثَوْبَيْنِ فَلْيُصَلِّي فِي ثَوْبٍ وَاحِدٍ مُلْتَحِفًا بِهِ فَإِنْ كَانَ الثَّوْبُ قَصِيرًا فَلْيَتَّزِرْ بِهِ .
Yahya related to me from Malik that he had heard from Jabir ibn Abdullah that the Messenger of Allah, (ﷺ), said, "Let anyone who cannot find two garments pray in one garment and wrap himself in it, and if the garment is short, let him wrap it around his waist." Malik said, "In my view it is preferable for someone who prays in a single shirt to put a garment or a turban over his shoulders."
