Arabic (Original)
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا سُفْيَانُ عَنْ زُبَيْدٍ عَنْ ذَرٍّ الْهَمْدَانِيِّ عَنْ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى الْخُزَاعِيِّ عَنْ أَبِيهِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُوتِرُ بِسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى وَقُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللَّهُ أَحَدٌ وَيَقُولُ إِذَا جَلَسَ فِي آخِرِ صَلَاتِهِ سُبْحَانَ الْمَلِكِ الْقُدُّوسِ ثَلَاثًا يَمُدُّ بِالْآخِرَةِ صَوْتَهُ.
English Translation
Waki' told us, Sufyan told us, from Zubayd, from Dharr al-Hamdani, from Sa'id ibn Abd al-Rahman ibn Abza al-Khuza'i, from his father, that the Prophet, peace and blessings be upon him, used to perform the witr prayer with "Glorify the Name of your Lord, the Most High," "Say: O disbelievers," and "Say: He is Allah, One"; and when he sat at the end of his prayer he would say "Glory be to the King, the Most Holy," three times, prolonging his voice on the last one.
