حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سُلَيْمَانَ بْنِ الأَشْعَثِ ، ثنا عَلِيُّ بْنُ خَشْرَمٍ ، ثنا عِيسَى بْنُ يُونُسَ ، عَنْ فِطْرٍ ، عَنْ زُبَيْدٍ ، عَنْ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى ، عَنْ أَبِيهِ ، عَنْ أُبَيِّ بْنِ كَعْبٍ ، قَالَ : " كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُوتِرُ بِثَلاثٍ بِ سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى ، وقُلْ يَا أَيُّهَا الْكَافِرُونَ ، وقُلْ هُوَ اللَّهُ أَحَدٌ ، وَيَقْنُتُ قَبْلَ الرُّكُوعِ ، وَإِذَا سَلَّمَ قَالَ : سُبْحَانَ الْمَلِكِ الْقُدُّوسِ ، ثَلاثَ مَرَّاتٍ يَمُدُّ بِهَا صَوْتَهُ ، فِي الأَخِيرَةِ يَقُولُ : رَبِّ الْمَلائِكَةِ وَالرُّوحِ " .
Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) used to recite "Surah Al-A'la," "Surah Al-Kafirun," and "Surah Al-Ikhlas" in the three rak'ahs of Witr, and he would recite the Qunoot supplication before going into bowing (ruku'). Then, when he finished with salam, he would say "Subhana al-Malik al-Quddus," and in the last time he would raise his voice, and he would say: "Rabb al-mala'ikati wa al-ruh," meaning "Lord of the angels and the spirit."
