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 يَقْرَأُ فِي الْوِتْرِ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ فَإِذَا سَلَّمَ قَالَ «سُبْحَانَ الْمَلِكِ الْقُدُّوسِ» ثَلَاثَ مَرَّاتٍ [269] خَالَفَهُ عَطَاءُ بْنُ السَّائِبِ فَلَمْ يَذْكُرْ أُبَيًّا  

[Machine] The Prophet ﷺ used to say in the last part of his night prayer: "Glory be to the King, the Holy." He would repeat this three times and Zubeid (may Allah be pleased with him) agreed with him.  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ فِي آخِرِ وِتْرِهِ «سُبْحَانَ الْمَلِكِ الْقُدُّوسِ» ثَلَاثَ مَرَّاتٍ يَمُدُّ فِي آخِرِهِنَّ وَافَقَهُ زُبَيْدٌ

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 يُوتِرُ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ وَإِذَا سَلَّمَ قَالَ «سُبْحَانَ الْمَلِكِ الْقُدُّوسِ» ثَلَاثَ مَرَّاتٍ يَمُدُّ صَوْتَهُ فِي الثَّالِثَةِ وَيَرْفَعُ أَرْسَلَهُ مَالِكُ بْنُ مِغْوَلٍ  

[Machine] The Messenger of Allah ﷺ used to perform the Witr prayer by reciting Surahs such as "Glorify the name of your Lord, the Most High" and "Say, O disbelievers". He would also recite "Say: He is Allah, the One". When he finished, he would say "Glory be to the King, the Holy" three times, raising his voice during the last repetition. Muhammad ibn Juhaadah went against this practice and narrated it from Zubeid, who narrated it from Ibn Abza, but he did not mention anything after that.  

كَانَ رَسُولُ اللهِ ﷺ يُوتِرُ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ فَإِذَا فَرَغَ قَالَ «سُبْحَانَ الْمَلِكِ الْقُدُّوسِ» ثَلَاثًا يَمُدُّ صَوْتَهُ بِالْآخِرَةِ [270] خَالَفَهُمَا مُحَمَّدُ بْنُ جُحَادَةَ فَرَوَاهُ عَنْ زُبَيْدٍ عَنِ ابْنِ أَبْزَى وَلَمْ يَذْكُرْ ذَرًّا  

"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 had finished praying, he said: Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy) three times." (Using translation from Nasāʾī 1736)  

كَانَ رَسُولُ اللهِ ﷺ يُوتِرُ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللهُ أَحَدٌ فَإِذَا فَرَغَ مِنَ الصَّلَاةِ قَالَ «سُبْحَانَ الْمَلِكِ الْقُدُّوسِ» ثَلَاثَ مَرَّاتٍ
