Take extra precautions when storing food or drinks; Close all doors before going to bed each night .

This hadith is about the importance of taking care to cover food and drinks, as well as closing doors at night. It was narrated by Abu Humaid Sa'idi that he came to Allah's Messenger with a cup of milk from Naqi' which had no cover over it, whereupon he said "Why did you not cover it? Even if you had covered it only with a stick." He was then instructed to tie waterskins during the night, and close the doors during the night. This teaches us that we should take extra precautions when storing food or drinks in order to protect them from dirt or other contaminants. Additionally, we should also make sure our homes are secure by closing all doors before going to bed each night.
