أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ الصَّمَدِ، قَالَ حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ عَزْرَةَ، عَنْ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَيُوتِرُ بِـ ‏‏{‏ سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى ‏}‏ وَ ‏‏{‏ قُلْ يَا أَيُّهَا الْكَافِرُونَ ‏}‏ وَ ‏‏{‏ قُلْ هُوَ اللَّهُ أَحَدٌ ‏}‏ وَإِذَا فَرَغَ قَالَ ‏"‏ سُبْحَانَ الْمَلِكِ الْقُدُّوسِ ‏"‏ ‏.‏ أَرْسَلَهُ هِشَامٌ ‏.‏
Translation
It was narrated from Ibn Abdur-Rahman bin Abza from his father that

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 after he had said the salam, he would say: Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy).
