حَدَّثَنَا سُفْيَانُ عَنِ الزُّهْرِيِّ عَنْ سَالِمٍ عَنْ أَبِيهِ رِوَايَةً وَقَالَ مَرَّةً يَبْلُغُ بِهِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا تَتْرُكُوا النَّارَ فِي بُيُوتِكُمْ حِينَ تَنَامُونَ

It was narrated from Saalim, from his father, who narrated it from his father and on one occasion attributed it to the Prophet (PBUH): "Do not leave any fire burning in your houses when you go to sleep."
