Abu Musa was between Makkah and Al-Madinah. He prayed 'Isha with two rak'ahs, then he stood and prayed one rak'ah of witr in which he recited one hundred verses from An-Nisa'. Then he said: "I tried my best to place my feet where the Messenger of Allah ﷺ placed his, and to recite what the Messenger of Allah ﷺ recited." (Using translation from Nasāʾī 1728)  

أَنَّ أَبَا مُوسَى كَانَ بَيْنَ مَكَّةَ وَالْمَدِينَةِ فَصَلَّى الْعِشَاءَ رَكْعَتَيْنِ ثُمَّ قَامَ فَصَلَّى رَكْعَةً أَوْتَرَ بِهَا فَقَرَأَ فِيهَا مِائَةَ آيَةٍ مِنَ النِّسَاءِ ثُمَّ قَالَ «مَا أَلَوْتُ أَنْ أَضَعَ قَدَمَيَّ حَيْثُ وَضَعَ رَسُولُ اللهِ ﷺ قَدَمَيْهِ وَأَنْ أَقْرَأُ بِمَا قَرَأَ بِهِ رَسُولُ اللهِ ﷺ»  

[Machine] I was at the house of Maymuna when the Prophet ﷺ stood up to pray at night. I stood up with him on his left side, and he took my hand and placed me on his right side. Then he prayed thirteen units of prayer, and I guessed the length of his standing in each unit, O you (Prophet) wrapped in garments.  

كُنْتُ فِي بَيْتِ مَيْمُونَةَ فَقَامَ النَّبِيُّ ﷺ «يُصَلِّي مِنَ اللَّيْلِ فَقُمْتُ مَعَهُ عَلَى يَسَارِهِ فَأَخَذَ بِيَدِي فَجَعَلَنِي عَنْ يَمِينِهِ ثُمَّ صَلَّى ثَلَاثَ عَشْرَةَ رَكْعَةً حَزَرْتُ قَدْرَ قِيَامِهِ فِي كُلِّ رَكْعَةٍ يَا أَيُّهَا الْمُزَّمِّلُ»  

“The Messenger of Allah ﷺ used to perform Witr and recite: ‘Glorify the Name of your Lord the Most High.’, [Al-A’la (87)] ‘Say: O you disbelievers!” [Al-Kafirun (109)] and ‘Say: Allah is One.”. [Al-Ikhlas (112)] (Using translation from Ibn Mājah 1171)   

أَنَّ النَّبِيَّ ﷺ كَانَ «يُوتِرُ بِسَبَّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ فِي رَكْعَةٍ رَكْعَةٍ»  

"The Messenger of Allah ﷺ used to pray witr with three rak'ahs. In the first he would recite "Glorify the Name of Your Lord, the Most High;" in the second: "Say: O You disbelievers!" and in the third: "Say: He is Allah, (the) One.'" (Using translation from Nasāʾī 1702)  

كَانَ رَسُولُ اللهِ ﷺ «يُوتِرُ بِثَلَاثٍ يُقْرَأُ فِي الْأُولَى بِسَبَّحِ اسْمَ رَبِّكَ الْأَعْلَى وَفِي الثَّانِيَةِ بِقُلْ يَا أَيُّهَا الْكَافِرُونَ وَفِي الثَّالِثَةِ بِقُلْ هُوَ اللهُ أَحَدٌ» وَقَفَهُ زُهَيْرُ بْنُ مُعَاوِيَةَ  

Ibn Abbas used to pray witr with three (units) with (the Surahs): "Glorify the Name of Your Lord, the Most High" (Surah Al-A'la), "Say: O You disbelievers" (Surah Al-Kafirun), and "Say: He is Allah, (the) One" (Surah Al-Ikhlas). (Using translation from Nasāʾī 1703)  

أَنَّهُ كَانَ يُوتِرُ بِثَلَاثٍ بِسَبَّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهَ أَحَدٌ  

Ubayy bin Ka'b said: "The Messenger of Allah ﷺ used to recite in Witr: "Glorify the Name of your Lord, the Most High;" and "Say: O you disbelievers!;' and 'Say: He is Allah, (the) One.' And when he said the salam, he would say: Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy) three times." (Using translation from Nasāʾī 1729)  

كَانَ رَسُولُ اللهِ ﷺ يُقْرَأُ فِي الْوِتْرِ بِسَبَّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ فَإِذَا سَلَّمَ قَالَ «سُبْحَانَ الْمَلَكِ الْقُدُّوسِ» ثَلَاثَ مَرَّاتٍ خَالَفَهُ حُصَيْنُ  

The Messenger of Allah ﷺ used to recite in Witr: "Glorify the Name of your Lord, the Most High;" and "Say: O you disbelievers!;' and 'Say: He is Allah, (the) One.'" (Using translation from Nasāʾī 1731)   

أَنَّ رَسُولَ اللهِ ﷺ كَانَ «يَقْرَأُ فِي الْوِتْرِ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ» تَابَعَهُ عَطَاءُ بْنُ السَّائِبِ

أَنَّ النَّبِيَّ ﷺ كَانَ «يَقْرَأُ فِي الْوِتْرِ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ»
