قَالَ النَّبِيُّ صلى الله عليه وسلم ((إِذَا كَانَ جُنْحُ اللَّيْلِ – أَوْ أَمْسَيْتُم – فَـكُفُّوا صِبْيانَـكُم، فَإِنَّ الشَّيَاطِينَ تَنْتَشِرُ حِينَئِذٍ، فَإِذَا ذَهَبَ سَاعَةٌ مِنَ اللَّيلِ فَخَلُّوهُمْ، وَأَغْلِقُوا الأَبْوَابَ وَاذْكُرُوا اسْمَ اللَّهِ؛ فَإِنَّ الشَّيطَانَ لاَ يَفْتَحُ بَاباً مُغلَقاً، وَأَوْكُوا قِرَبَكُمْ، وَاذْكُرُوا اسْمَ اللَّهِ، وَخَمِّرُوا آنِيَتَكُم، وَاذْكُرُوا اسْمَ اللَّهِ، وَلَوْ أَنْ تَعْرُضُوا عَلَيْهَا شَيْئاً، وَأَطْفِئُوا مَصَابِيحَكُمْ)).
When evening descends, bring your children indoors for the devils scatter out at this hour. Then after the passing of an hour (i.e. the first hour) of the night, (you may) let them (the children) go. Close your doors while mentioning the Name of Allah, for the devil may not open a closed door. Fasten your waterskins mentioning the Name of Allah. Cover your eating vessels mentioning the Name of Allah even if you just put something over it, and extinguish your lamps. Peace and blessing be upon our Prophet, Muhammad, and upon his family and his Companions, all of them.
