Narrated AbuQatadah: The Prophet (ﷺ) asked AbuBakr: 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 AbuBakr: This has followed it with care; and he said to Umar: He has followed it with strength.
