Be careful when eating food so you don't consume anything harmful or unclean; Remove whatever caused contamination before consuming; Do not waste food even if its contaminated by something else.

This hadith is about eating food that has been contaminated by something else. In this case, a mouse fell into clarified butter, which is a type of food. The Prophet was informed of this and he advised to throw away what was around the mouse and still eat the rest. This teaches us that we should not waste food even if it has been contaminated by something else, as long as we can make sure to remove whatever caused the contamination. We should also be careful when eating food so that we do not consume anything harmful or unclean.
