It is narrated from Ibn Muhairiz (may Allah have mercy on him) that a man from Banu Kinanah, Mukhdaaji, heard Abu Muhammad in Syria saying that Witr is obligatory. Mukhdaaji said: Then I went to Sayyiduna Ubadah bin As-Samit (may Allah be pleased with him). When I came face to face with him, he was going to the mosque. Then I told him what Abu Muhammad had said, so Ubadah (may Allah be pleased with him) said: Abu Muhammad has spoken incorrectly. I heard the Messenger of Allah (peace and blessings be upon him) say that Allah has made five prayers obligatory upon His servants. So whoever brings them (on the Day of Judgment), not having neglected any of their rights out of disdain, then Allah has promised to admit him to Paradise. And whoever does not bring them, having neglected their rights out of disdain, then Allah has no promise with him. If He wills, He will punish him, and if He wills, He will admit him to Paradise.
