عن ابن عمر رضي الله عنهما عن النبي صلى الله عليه وسلم قال‏:‏ ‏"‏لا تتركوا النار في بيوتكم حين تنامون‏"‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

Abu Musa Al-Ash'ari (May Allah be pleased with him) said

A house in Al-Madinah was burnt with its occupants inside it one night. When this was reported to the Messenger of Allah (ﷺ) he said, "Fire is your enemy. So, put it out before going to bed."[Al-Bukhari and Muslim].
