Narrated Abu Qatadah: The Prophet ﷺ asked Abu Bakr: When do you observe the witr? He replied: I observe the witr prayer in the early hours of the night. The Prophet ﷺ asked Umar: When do you observe the witr? He replied: At the end of the night. He then said to Abu Bakr: This has followed it with care; and he said to Umar: He has followed it with strength.

1434. Commentary: A person should always act with confidence. If waking up at the end of the night seems difficult, then one should perform the witr prayer before sleeping. And in the morning, upon waking, perform the tahajjud prayer. There is no need to repeat the witr.
