[Machine] Ibn 'Umar used to say: "Whoever prays at night should make his last prayer odd number of units, for the Messenger of Allah ﷺ ordered that. When dawn breaks, the night prayer and the witr prayer are no longer valid, because the Messenger of Allah ﷺ said: 'Perform the witr prayer before dawn.' And in another narration: 'Perform the witr prayer with the dawn prayer.'"

[Machine] "Narrated Ibn Umar that he used to say: 'Whoever prays at night, let him make Witr as his last prayer. For indeed, the Messenger of Allah ﷺ commanded that. And when dawn comes, all the night prayers and Witr are gone. For indeed, the Messenger of Allah ﷺ said: 'Perform Witr before dawn.'
