"Witr is not essential like the obligatory prayers, but it is the sunnah of the Messenger of Allah ﷺ."  

الْوِتْرُ لَيْسَ بِحَتْمٍ كَهَيْئَةِ الْمَكْتُوبَةِ وَلَكِنَّهُ سُنَّةٌ سَنَّهَا رَسُولُ اللَّهِ ﷺ  

Witr is not a must, but it is a Sunnah that was established by the Messenger of Allah ﷺ .  

الْوَتْرُ لَيْسَ بِحَتْمٍ وَلَكِنَّهُ سُنَّةٌ سَنَّهَا رَسُولُ اللهِ ﷺ  

[Machine] "Witr is not an obligatory prayer like the prescribed prayers, but it is a recommended sunnah that the Messenger of Allah ﷺ established. He said, 'Perform Witr, O people of the Quran, for indeed Allah, the Exalted, is odd and He loves the odd-numbered prayer.'"  

الْوِتْرُ لَيْسَ بِحَتْمٍ كَالصَّلَاةِ الْمَكْتُوبَةِ وَلَكِنَّهُ سُنَّةٌ سَنَّهَا رَسُولُ اللهِ ﷺ فَقَالَ أَوْتِرُوا يَا أَهْلَ الْقُرْآنِ فَإِنَّ اللهَ تَعَالَى وِتْرٌ يُحِبُّ الْوِتْرَ
