حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَمْرٌو النَّاقِدُ، وَزُهَيْرُ بْنُ حَرْبٍ، قَالُوا حَدَّثَنَا سُفْيَانُ، بْنُ عُيَيْنَةَ عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ تَتْرُكُوا النَّارَ فِي بُيُوتِكُمْ حِينَ تَنَامُونَ " .
Salim, on the authority of his father, reported Allah's Messenger (ﷺ) having said: Do not leave the fire burning in your houses when you go to sleep.
