CHAPTER: The Time Of The Witr Prayer.
Masruq said: I asked Aishah: When would the Messenger of Allah صلی اللہ علیہ وسلم observe the witr prayer ? She replied: Any time he observed the witr, sometimes in the early hours of the night, sometimes at midnight and sometimes towards the end of it. But he used to observe the witr just before the dawn when he died.
Ibn Umar reported the Prophet صلی اللہ علیہ وسلم as saying: Make haste to observe the witr prayer before morning.
Abdullah bin Abu Qais said: I asked Aishah about the witr observes by the Messenger of Allah صلی اللہ علیہ وسلم. She replied: Sometime he observed the witr prayer in the early hours of the night, sometimes he observed it at the end of it. I asked: How did he recite the Quran ? Did he recite the Quran quietly or loudly ? She replied: He did it in any way. Sometimes he recited quietly and sometimes loudly, sometimes he took bath and then slept and sometimes he performed ablution and then slept. Abu Dawud said: The narrators other than Qutaibah said: This refer to his bath due to sexual defilement.
Ibn Umar reported the Prophet صلی اللہ علیہ وسلم as suing: Make the last of your prayer at night a witr.
