If one can cover the cooking pot even by placing a piece of wood across it, and pronounce the Name of Allah on it, let him do it. The Ahadith mentioned above stress the fact that one must put out the fire before going to bed, no matter whether this fire is in the form of a lamp, a fireplace, or a heater.
Experience shows that leaving the fire alive sometime proves very dangerous.
Leaving the utensils, water-skins, pitchers etc., uncovered must also be avoided to prevent them from dirt and insects which can cause harm. Similarly, doors and windows should also be kept closed while one is sleeping in order to guard the house against thieves and robbers. One must recite the Name of Allah, that is to say Bismillah, before using and keeping things.
