It was narrated that ‘Abdul-‘Aziz bin Juraij said:“We asked ‘Aishah what the Messenger of Allah (ﷺ) used to recite in Witr. She said: ‘He used to recite: “Glorify the Name of your Lord the Most High,” [Al-A’la (87)] in the first Rak’ah, ‘Say: “O disbelievers!’” [Al- Kafirun (109)] in the second Rak’ah, and ‘Say: Allah is One’ in the third and the Mu’awwidhatain (Chapter 113, 114).’”
