The Book of Virtues
Witr Prayer, its Time and Ruling
عَنْ عَلِيٍّ رَضِيَ اللَّه عَنْهُ قَالَ: الوتر ليس بختم كصلاة الْمَكْتُوبَةِ وَلَكِنْ سَنَّ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: إِنَّ اللَّهَ وِتْرٌ يُحِبُّ الْوِتْرَ، فَأَوْتِرُوا يَا أَهْلَ الْقُرْآنِ . ((رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ)). وَقَالَ: حَدِيث حَسَن.
'Ali (bin Abu Talib) (May Allah be pleased with him) reported: The Witr prayer is not obligatory as the prescribed Salat (prayers), but the Messenger of Allah (ﷺ) observed it as his regular practice (Sunnah). He (ﷺ) said, "Allah is Witr (single, odd) and loves what is Witr. So perform Witr prayer. O followers of Qur'an, observe Witr (prayer)." [At-Tirmidhi and Abu Dawud].
