996 - Narrated ‘Aishah (may Allah be pleased with her): Allah's Messenger ﷺ offered Witr prayer (on different nights) at various hours, extending (from the 'Ishaa' prayer) up to the last hour of the night..

Commentary : The Prophet ﷺ used to pray so much at night, and encouraged us to perform the Witr prayer, and to make it the last prayer at night.

In this hadeeth, ‘Aishah (may Allah be pleased with her) expounds on the manner of the Prophet ﷺ towards the Witr prayer. The Mother of the Believers, ‘Aishah, was the most knowledgeable person of the prayer of the Messenger of Allah ﷺ at night; she was his wife and witnessed what other people were not able to in relation to his prayers at night. She learned its times, counted the number of its units, its [various] forms, and so forth.

She reported that the time of the prayer of the Prophet ﷺ varied with regards to Witr. Sometimes, he prayed it at the first part of the night; other times he prayed it in the middle of night; and some other times, he prayed it at its end. The reason he prayed it at different time is to make ease and accommodation towards his nation; thus, it is possible to offer the Witr prayer at any time of the night. However, the time of night during which the Prophet ﷺ eventually settled on to offer the Witr prayer was near the time before the appearance of morning twilight.

From this hadeeth we learn that the time of the Witr prayer extends [from the first part of the night] to before Fajr prayer, and that the minimum [number of prayer units] for the Witr prayer is one unit or three.
