Perform wudu when you are sexually defiled before sleeping.

According to the hadith reported by A'ishah, the Prophet Muhammad ﷺ would perform ablution when he was sexually defiled before sleeping. This is a sign of his great piety and devotion to Allah, as well as an example of how Muslims should strive to maintain cleanliness and purity in all aspects of their lives. It is important for Muslims to remember that even if they are not able to pray due to being in a state of sexual defilement, they should still strive for cleanliness and purity by performing wudu. This hadith also serves as a reminder that we should always be mindful of our actions and strive for righteousness in all aspects of our lives.
