NASAI 1741:
from ʿAbd al-Raḥman b. Abzá —
"Abu Dawud narrated to us, he said: Shu'ba narrated to us, from Qatadah, from Abdur-Rahman bin Abza, 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 when he said the taslim, he would say: Subhanal-Malikil-Quddus (Glory be to the Sovereign, the Most Holy) three times, elongating his words the third time."
النسائي ١٧٤١:
عن عبد الرحمن بن ابزى —
عَنْ رَسُولِ اللَّهِ ﷺ كَانَ يُوتِرُ بِ { سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى } وَ { قُلْ يَا أَيُّهَا الْكَافِرُونَ } وَ { قُلْ هُوَ اللَّهُ أَحَدٌ } فَإِذَا فَرَغَ قَالَ سُبْحَانَ الْمَلِكِ الْقُدُّوسِ ثَلاَثًا وَيَمُدُّ فِي الثَّالِثَةِ
