CHAPTER: What Should Be Recited In Witr.
Narrated Ubayy ibn Kab: The Messenger of Allah صلی اللہ علیہ وسلم used to observe witr with (reciting) Glorify the name of thy Lord, the most High (Surah 87), Say O disbelievers (Surah 109), and Say, He is Allah, the One, Allah, the eternally besought of all (112).
Narrated Aishah, Ummul Muminin: Abdul Aziz ibn Jurayj said: I asked Aishah, mother of the believers: With which (surah) the Messenger of Allah صلی اللہ علیہ وسلم used to observe witr? (She reported same as in the Hadith of Ubayy ibn Kab, No. 1418) This version adds: In the third rak'ah he would recite: Say, He is Allah, the One (Surah 112), and Say, I seek refuge in the Lord of daybreak (Surah 113), and Say, I seek refuge in the Lord of mankind (Surah 114).
