1- What is the ruling regarding excess food? Is it permissible to discard it?

It is not permissible to discard edible food that is not spoiled. Rather, it must be given to the poor and needy, or preserved for other meals. It should only be discarded if there is a fear of harm from its consumption, or if people find it repulsive, in which case it should be given to domestic animals. A Muslim must be cautious of extravagance, which is spending on what is appropriate but in excess of what is needed, or spending on what is not appropriate at all. They must adhere to moderation in spending.
