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 ʿThe mutual rivalry (for piling up of worldly things) diverts youʿ [At-Takathur 102] and “verily, We have sent it (this Qurʿan) down in the Night of Al-Qadr (Decree)ʿ [al-Qadr 97], and ʿWhen the earth is shaken with its (final) earthquakeʿ [az-Zalzalah 99]. In the second rakʿah he would recite ʿBy Al-‘Asr (the time)” [Al-ʻAsr 103] and ʿWhen there comes the Help of Allah (to you, O Muhammad against your enemies) and the Conquest (of Makkah)ʿ [An-Nasr 95] and “Verily. We have granted you (O Muhammad ﷺ) Al-Kawthar (a river in Paradise)ʿ [Al-Kawthar 108]. In the third rakʿah he would recite “Say (O Muhammad to these Mushrikoon and Kafiroon): ʿO 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!ʿ [Al-Masad 109] and ʿSay (O Muhammad ﷺ): “He is Allah, (the) One“ [Al-Ikhlas 112].
