مُوَطَّأُ مَالِكٍ
Muwatta Malik 319
Prayer in Congregation
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عُمَرَ بْنِ أَبِي سَلَمَةَ، أَنَّهُ رَأَى رَسُولَ اللَّهِ صلى الله عليه وسلم يُصَلِّي فِي ثَوْبٍ وَاحِدٍ مُشْتَمِلاً بِهِ فِي بَيْتِ أُمِّ سَلَمَةَ وَاضِعًا طَرَفَيْهِ عَلَى عَاتِقَيْهِ .
Yahya related to me from Malik from Hisham ibn Urwa from his father that Umar ibn Abi Salama saw the Messenger of Allah, (ﷺ), praying in one garment in the house of Umm Salama. He was completely covered by it, and had put both ends over his shoulders.
