Perform wudu before sleeping

This hadith tells us that the Prophet Muhammad ﷺ used to sleep while he was in a state of ritual impurity, known as hadath. However, before going to bed, the Prophet ﷺ would always perform ablution or wudu. This teaches us that even though we may be in a state of ritual impurity, we should still take care of our hygiene and cleanliness by performing wudu before sleeping. It also shows us the importance of following the Sunnah and emulating the example set by our beloved Prophet ﷺ.
