ahmad:6190Yaʿqūb from my father > Ibn Isḥāq > Nāfiʿ > Ibn ʿUmar

[Machine] "To pray at night, I used to offer one Rak'ah (unit of prayer) after the completion of my Witr (odd) prayer. Then I would pray two Rak'ahs (units of prayer) again and again. And when I finished my prayer, I would perform one Rak'ah of Witr. Indeed, the Messenger of Allah ﷺ commanded that the last prayer at night be Witr."  

أحمد:٦١٩٠حَدَّثَنَا يَعْقُوبُ حَدَّثَنَا أَبِي عَنْ ابْنِ إِسْحَاقَ حَدَّثَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ أَنَّهُ كَانَ إِذَا سُئِلَ عَنِ الْوَتْرِ؟ قَالَ أَمَّا أَنَا فَلَوْ أَوْتَرْتُ قَبْلَ أَنْ أَنَامَ ثُمَّ أَرَدْتُ

أَنْ أُصَلِّيَ بِاللَّيْلِ شَفَعْتُ بِوَاحِدَةٍ مَا مَضَى مِنْ وِتْرِي ثُمَّ صَلَّيْتُ مَثْنَى مَثْنَى فَإِذَا قَضَيْتُ صَلَاتِي أَوْتَرْتُ بِوَاحِدَةٍ إِنَّ رَسُولَ اللهِ ﷺ أَمَرَ أَنْ يُجْعَلَ آخِرَ صَلَاةِ اللَّيْلِ الْوَتْرُ
