مسند أحمد

It was narrated that ‘Ali (رضي الله عنه) said: The Messenger of Allah (ﷺ) used to pray Witr reciting nine surahs from Al-Mufassal. Aswad said: In the first rak’ah he would recite `The mutual rivalry (for piling up of worldly things) diverts you` [At-Takathur 102] and “verily, We have sent it (this Qur`an) down in the Night of Al-Qadr (Decree)` [al-Qadr 97], and `When the earth is shaken with its (final) earthquake` [az-Zalzalah 99]. In the second rak`ah he would recite `By Al-‘Asr (the time)” [Al-ʻAsr 103] and `When there comes the Help of Allah (to you, O Muhammad against your enemies) and the Conquest (of Makkah)` [An-Nasr 95] and “Verily. We have granted you (O Muhammad (ﷺ)) Al-Kawthar (a river in Paradise)` [Al-Kawthar 108]. In the third rak`ah he would recite “Say (O Muhammad to these Mushrikoon and Kafiroon): `O Al-Kafiroon (disbelievers in Allah, in His Oneness, in His Angels, in His Books, in His Messengers, in the Day of Resurrection, and in Al Qadar)!” [Al-Kafiroon 109] and “Perish the two hands of Abu Lahab (an uncle of the Prophet (ﷺ)) and perish he!` [Al-Masad 109] and `Say (O Muhammad (ﷺ)): “He is Allah, (the) One“ [Al-Ikhlas 112].
