When night falls, restrain your children (from going out) because at such time the devils spread about. After a period of time has passed, let them be. Shut your doors and mention Allah’s name, for verily the devil does not open a shut door, tie up your water-skins and mention Allah’s name, cover your vessels with anything and mention Allah’s name and put out your lamps. Reference: Al-Bukhari with Al-Fath 10/88 and Muslim 3/1595.

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.
