مُوَطَّأُ مَالِكٍ
Muwatta Malik 262
Tahajjud
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 .
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 rakas in the night, making them odd by a single one, and when he had finished he lay down on his right side.
