(2) باب فِيمَنْ لَمْ يُوتِرْ
Narrated Buraydah ibn al-Hasib:
I heard the Messenger of Allah (ﷺ) say: The witr is a duty, so he who does not observe it does not belong to us; the witr is a duty, so he who does not observe it does not belong to us; the witr is a duty, so he who does not observe it does not belong to us. (TR)
