Chapter 2: How the Prophet, may Allah bless him and grant him peace, Prayed the Witr
Muwatta Malik 265
Yahya related to me from Malik from Ibn Shihab from Urwa ibn az- Zubayr from A'isha, the wife of the Prophet ﷺ that the Messenger of Allah ﷺ used to pray eleven Rak'ahs in the night, making them odd by a single one, and when he had finished he lay down on his right side.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم . أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي مِنَ اللَّيْلِ إِحْدَى عَشْرَةَ رَكْعَةً يُوتِرُ مِنْهَا بِوَاحِدَةٍ فَإِذَا فَرَغَ اضْطَجَعَ عَلَى شِقِّهِ الأَيْمَنِ .
