'A'isha reported that the Messenger of Allah ﷺ used to offer prayer at night while she lay in front of him, and when the Witr prayer was yet to be observed, he would awaken her and she observed Witr.
This hadith also teaches us about being mindful of our religious obligations and taking them seriously no matter what situation we are in or how tired we may be feeling. We should always strive to fulfill our duties towards Allah SWT with sincerity and dedication as this is one way through which we can gain His pleasure and mercy upon us all.
