Mukhtasar Bukhari (Abridged) 1387 — Description of Iblis and his army

Narrated by Sayyiduna Jabir (may Allah be pleased with him) from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "When the darkness of night falls, keep your children inside the house, for at that time the devils spread out. When an hour of the night prayer (Isha) has passed, then let the children go (to walk around). And close your door by saying 'Bismillah' (in the name of Allah), and extinguish your lamp by saying 'Bismillah' (i.e., extinguish every kind of fire), and cover your water vessel (pitcher, cooler, underground tank, etc.) by saying 'Bismillah'. If you do not find anything to cover it with, then place a stick or something similar over it."
