[Machine] The Prophet ﷺ used to recite in Witr prayer, in the first Rak'ah, "Glorify the name of your Lord, the Most High." In the second Rak'ah, he would recite "Say: O disbelievers." In the third Rak'ah, he would recite "Say: He is Allah, the One" and "Say: I seek refuge in the Lord of the daybreak." Lastly, he would recite "Say: I seek refuge in the Lord of mankind."  

كَانَ النَّبِيُّ ﷺ يَقْرَأُ فِي الْوِتْرِ فِي الرَّكْعَةِ الْأُولَى سَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَفِي الثَّانِيَةِ قُلْ يَا أَيُّهَا الْكَافِرُونَ وَفِي الثَّالِثَةِ قُلْ هُوَ اللَّهُ أَحَدٌ وَقُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَقُلْ أَعُوذُ بِرَبِّ النَّاسِ  

[Machine] We asked Aisha, "What used to the Messenger of Allah ﷺ recite during the Witr prayer?" She replied, "In the first Rak'ah, he used to recite Surah Al-A'la (the Most High), in the second Rak'ah, Surah Al-Kafirun (the Disbelievers), and in the third Rak'ah, Surah Al-Ikhlas (the Unity) along with Surah Al-Falaq (the Dawn) and Surah An-Nas (Mankind)." Sa'id ibn Kathir ibn 'Ufair, who is a narrating authority among the people of Egypt, mentioned this Hadith and narration. I requested it at the time when I was writing a book about Witr prayer, but I did not find it. Later, I found it after Adh-Dhahabi stopped commenting on it in his summary.  

سَأَلْنَا عَائِشَةَ بِأَيِّ شَيْءٍ كَانَ يَقْرَأُ رَسُولُ اللَّهِ ﷺ فِي الْوِتْرِ؟ فَقَالَتْ «كَانَ يَقْرَأُ فِي الرَّكْعَةِ الْأُولَى بِسَبِّحِ اسْمَ رَبِّكِ الْأَعْلَى وَفِي الثَّانِيَةِ بِقُلْ يَا أَيُّهَا الْكَافِرُونَ وَفِي الثَّالِثَةِ بِقُلْ هُوَ اللَّهُ أَحَدٌ وَالْمُعَوِّذَتَيْنِ» قَدْ أَتَى إِمَامُ أَهْلِ مِصْرَ فِي الْحَدِيثِ وَالرِّوَايَةِ سَعِيدُ بْنُ كَثِيرِ بْنِ عُفَيْرٍ عَنْ يَحْيَى بْنِ أَيُّوبَ طَلَبْتُهَا وَقْتَ إِمْلَائِي كِتَابَ الْوِتْرِ فَلَمْ أَجِدْهَا فَوَجَدْتُهَا بَعْدُ سكت عنه الذهبي في التلخيص  

[Machine] The Messenger of Allah ﷺ used to perform two units of prayer, followed by Witr prayer wherein he would recite after them "Exalt the name of your Lord, the Most High" and "Say: O disbelievers!" And in Witr prayer, he would recite "Say: He is Allah, the One" and "Say: I seek refuge in the Lord of the daybreak" and "Say: I seek refuge in the Lord of mankind."  

«كَانَ رَسُولُ اللَّهِ ﷺ فِي الرَّكْعَتَيْنِ اللَّتَيْنِ يُوتِرُ بَعْدَهُمَا بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَيَقْرَأُ فِي الْوِتْرِ بِقُلْ هُوَ اللَّهُ أَحَدٌ وَقُلْ أَعُوذُ بِرَبِّ الْفَلَقِ وَقُلْ أَعُوذُ بِرَبِّ النَّاسِ»  

[Machine] He used to say, when he recited, "Exalt the name of your Lord, the Most High" [Al-A'la 1], he said, "Glory be to my Lord, the Most High, who created and proportioned." He said, and this is the recitation of Ubayy ibn Ka'b.  

أَنَّهُ كَانَ إِذَا قَرَأَ {سَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى} [الأعلى 1] قَالَ «سُبْحَانَ رَبِّيَ الْأَعْلَى الَّذِي خَلَقَ فَسَوَّى» قَالَ وَهِيَ قِرَاءَةُ أُبَيِّ بْنِ كَعْبٍ  

[Machine] Saad, indeed the Quran did not come down upon Musayyib nor upon the family of Musayyib. Allah Almighty said, "We will make you recite, so you shall not forget" [Al-Quran, 87:6]. And He said, "And remember your Lord when you forget" [Surah Al-Kahf, 18:24].  

سَعْدٌ إِنَّ الْقُرْآنَ لَمْ يَنْزِلْ عَلَى الْمُسَيِّبِ وَلَا عَلَى آلِ الْمُسَيِّبِ قَالَ اللَّهُ ﷻ {سَنُقْرِئُكَ فَلَا تَنْسَى} وَقَالَ {وَاذْكُرْ رَبَّكَ إِذَا نَسِيتَ} [الكهف 24]
