وَعَنْ أَبِي مُوسَى اَلْأَشْعَرِيِّ رَضِيَ اللَّه عَنْهُ قَالَ: احْتَرَقَ بَيْتٌ بِالْمَدِينَةِ عَلَى أَهْلِهِ مِنَ اللَّيْلِ، فَلَمَّا حُدِّثَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ بِشَأْنِهِمْ قَالَ: إِنَّ هَذِهِ النَّارَ عَدُوٌّ لَكُمْ، فَإِذَا نِمْتُمْ فَأَطْفِئُوهَا ((مُتَّفَقٌ عَلَيْهِ)).
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].
