Put out any open flames before sleeping.

This hadith from Ibn 'Umar advises people to not keep a fire burning in their homes when they go to bed. This is an important safety precaution as it can prevent fires from starting and spreading while people are asleep. It is important for everyone, especially those with young children or elderly family members, to take this advice seriously and make sure that all fires are put out before going to sleep. Additionally, it is also important for people who live in areas where there are frequent power outages or other issues that could cause a fire hazard to be extra vigilant about making sure all fires are extinguished before going to bed.
