Is my feeling correct that the food I eat and the money I earn are unlawful due to their source, making my hard work unlawful, even though I don't own a home and am striving to acquire one?

This feeling is incorrect. Eating from ill-gotten wealth does not necessitate that what the eater earns from a permissible job becomes illicit money. Legitimate work yields lawful earnings, even if the food prepared by the mother is a mix of lawful and unlawful (money from cigarettes and taking money without the husband's knowledge). It is important to note that the mother's maintenance is obligatory upon the father, and if he withholds it, she is permitted to take what suffices her without his knowledge. The mother should be advised to abandon selling cigarettes and turn to earning a lawful livelihood.
