(205) Chapter: Witr Prayer, its Time and Ruling

Jabir (May Allah be pleased with him)reported: The Messenger of Allah (ﷺ) said, "He who apprehends that he may not get up in the later part of the night, should observe the Witr prayer in the first part of it; and he who is certain to get up in the last part of it, he should observe Witr at the end of the night, because Salat at the end of the night is attended (by the angels), and that is better." [Muslim]. Commentary: If a person is confident that he will get up to perform Witr prayer before dawn, it is better for him to perform it in the late hours of the night; otherwise, it will be well to do so after `Isha' prayer.
