Narrated Aisha, Ummul Mu'minin:
AbdulAziz ibn Jurayj said: I asked Aisha, mother of the believers: With which (surah) the Messenger of Allah (ﷺ) used to observe witr? (She reported same as in the Hadith of Ubayy ibn Ka'b, 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).
حَدَّثَنَا أَحْمَدُ بْنُ أَبِي شُعَيْبٍ، حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ، حَدَّثَنَا خُصَيْفٌ، عَنْ عَبْدِ الْعَزِيزِ بْنِ جُرَيْجٍ، قَالَ سَأَلْتُ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ بِأَىِّ شَىْءٍ كَانَ يُوتِرُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَذَكَرَ مَعْنَاهُ قَالَ وَفِي الثَّالِثَةِ بِـ { قُلْ هُوَ اللَّهُ أَحَدٌ } وَالْمُعَوِّذَتَيْنِ .
