(12) باب الأَمْرِ بِتَغْطِيَةِ الإِنَاءِ وَإِيكَاءِ السِّقَاءِ وَإِغْلاَقِ الأَبْوَابِ وَذِكْرِ اسْمِ اللَّهِ عَلَيْهَا وَإِطْفَاءِ السِّرَاجِ وَالنَّارِ عِنْدَ النَّوْمِ وَكَفِّ الصِّبْيَانِ وَالْمَوَاشِي بَعْدَ الْمَغْرِبِ
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.
