What is the ruling on returning food despite feeling hungry and sensing that Allah will hold one accountable for this blessing?

Spoiling food is a forbidden sin, because it is a form of extravagance, which the Holy Quran and the Prophet's Sunnah (definition) have prohibited. A Muslim must be moderate in eating and drinking, as the Prophet, peace and blessings be upon him, said: "The son of Adam fills no vessel worse than his stomach. A few morsels are sufficient for the son of Adam to keep his back straight. But if he must eat, then a third for his food, a third for his drink, and a third for his breath." Deliberately inducing vomiting is disliked (makrooh), and it becomes forbidden (haram (definition)) if it causes harm to the body, based on the Prophet's saying: "There should be neither harm nor reciprocating harm," and Allah's saying: "And do not throw [yourselves] with your [own] hands into destruction." Showing gratitude for blessings is obligatory, and wasting them contradicts this. Allah will question about wealth: from where one acquired it and on what one spent it.
