And Salamah ibn Shabib narrated to me, saying: Al-Hasan ibn A'yan narrated to us, saying: Ma'qil—and he is Ibn 'Ubaydullah—narrated to us, from Abu al-Zubayr, from Jabir, who said: I heard the Prophet, peace and blessings be upon him, say: "Whoever among you fears that he will not get up at the end of the night, let him pray Witr, then sleep. And whoever is confident that he will get up during the night, let him pray Witr at its end, for the recitation at the end of the night is witnessed, and that is more virtuous."
