وَعَنْهَا قَالَتْ: «كَانَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّي مِنْ اَللَّيْلِ ثَلَاثَ عَشْرَةَ رَكْعَةً، يُوتِرُ مِنْ ذَلِكَ بِخَمْسٍ، لَا يَجْلِسُ فِي شَيْءٍ إِلَّا فِي آخِرِهَا»
The Messenger of Allah (sallallahu alayhi wa sallam) used to pray thirteen Rakat during the night, offering a Witr out of that with five and sitting only during the last of them.
