The Book on Al-Witr
3/2. Chapter:
What Has Been Related About Al-Witr Is Not Incumbent
Jami at-Tirmidhi
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو بَكْرِ بْنُ عَيَّاشٍ، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ عَاصِمِ بْنِ ضَمْرَةَ، عَنْ عَلِيٍّ، قَالَ الْوِتْرُ لَيْسَ بِحَتْمٍ كَصَلاَتِكُمُ الْمَكْتُوبَةِ وَلَكِنْ سَنَّ رَسُولُ اللَّهِ صلى الله عليه وسلم وَقَالَ " إِنَّ اللَّهَ وِتْرٌ يُحِبُّ الْوِتْرَ فَأَوْتِرُوا يَا أَهْلَ الْقُرْآنِ " . قَالَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ وَابْنِ مَسْعُودٍ وَابْنِ عَبَّاسٍ . قَالَ أَبُو عِيسَى حَدِيثُ عَلِيٍّ حَدِيثٌ حَسَنٌ .
Ali said: "Al-Witr Is Not Incumbent Like Your Obligatory Prayers, But It Is A Sunnah Of Allah'S Messenger Who Said: "Indeed Allah Is Witr (One), And He Loves Al-Witr, So Perform Al-Witr O People Of The Qur'An."
