Arabic (Original)
حَدَّثَنَا يَزِيدُ أَخْبَرَنَا هِشَامٌ عَنْ مُحَمَّدٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ صَلَاةُ الْمَغْرِبِ وِتْرُ النَّهَارِ فَأَوْتِرُوا صَلَاةَ اللَّيْلِ.
English Translation
Yazid narrated to us: Hisham informed us, from Muhammad, from Ibn Umar, from the Prophet, peace and blessings be upon him, that he said: The sunset prayer is the witr of the day, so make the night prayer witr as well.
