A man from Banu Kinana, whose name was Mukhdaaji, narrates that an Ansari companion in Syria, Abu Muhammad, used to say that Witr is obligatory. Mukhdaaji says that when this was mentioned in the presence of Hazrat Ubadah bin Samit, Hazrat Ubadah said, "Abu Muhammad is lying. I heard the Messenger of Allah (peace and blessings be upon him) say that there are five prayers which Allah has made obligatory upon His servants. Whoever performs these prayers without neglecting their due rights, it is incumbent upon Allah to admit him to Paradise. Whoever falls short in fulfilling their rights, Allah has no responsibility towards him; if He wills, He may punish him, and if He wills, He may admit him to Paradise."
