Brief Explanation
Benefits: … There are great benefits for people in fire, but just like an enemy, one can never be completely safe from its harm. It has burned many people, burned houses, and burned the belongings within houses. Therefore, when going to sleep, one should extinguish any fire present inside the house before sleeping.
