Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّزَّاقِ وَابْنُ بَكْرٍ قَالَا أَخْبَرَنَا ابْنُ جُرَيْجٍ حَدَّثَنِي سُلَيْمَانُ بْنُ مُوسَى حَدَّثَنَا نَافِعٌ أَنَّ ابْنَ عُمَرَ كَانَ يَقُولُ مَنْ صَلَّى بِاللَّيْلِ فَلْيَجْعَلْ آخِرَ صَلَاتِهِ وِتْرًا فَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِذَلِكَ فَإِذَا كَانَ الْفَجْرُ فَقَدْ ذَهَبَتْ كُلُّ صَلَاةِ اللَّيْلِ وَالْوَتْرُ فَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ أَوْتِرُوا قَبْلَ الْفَجْرِ.
English Translation
Abdur-Razzaq and Ibn Bakr told us, they said: Ibn Jurayj informed us: Sulayman ibn Musa told me, Nafi' told us, that Ibn Umar used to say: Whoever prays at night should make the last of his prayer witr, for the Messenger of Allah (peace and blessings be upon him) commanded that; and when dawn comes, all night prayer and the witr have passed, for the Messenger of Allah (peace and blessings be upon him) said: Pray witr before dawn.
