"Do not leave fire in your houses when you go to sleep."  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ تَتْرُكُوا النَّارَ فِي بُيُوتِكُمْ حِينَ تَنَامُونَ  

"A house burned down in Al-Madinah, with its occupants inside. The Prophet ﷺ was told of what had happened, and he said: 'This fire is an enemy to you. When you go to sleep, extinguish it.'"  

احْتَرَقَ بَيْتٌ بِالْمَدِينَةِ عَلَى أَهْلِهِ فَحُدِّثَ النَّبِيُّ ﷺ بِشَأْنِهِمْ فَقَالَ إِنَّمَا هَذِهِ النَّارُ عَدُوٌّ لَكُمْ فَإِذَا نِمْتُمْ فَأَطْفِئُوهَا عَنْكُمْ  

"The Messenger of Allah ﷺ commanded us (to do some things) and forbade us (to do some things), and he commanded us to extinguish our lamps."  

أَمَرَنَا رَسُولُ اللَّهِ ﷺ وَنَهَانَا فَأَمَرَنَا أَنْ نُطْفِئَ سِرَاجَنَا
