Is it permissible for two sisters to refrain from eating the food prepared by their husbands, one of whom works as a driver for a bank and the other in the maintenance of a hotel that serves alcoholic beverages, and is it permissible to give them from Zakat if their action is correct?

The earnings of a husband and wife from their work, such as a driver in a bank or a maintenance employee in a hotel where alcohol is served, are illicit earnings. This is because their work falls under the category of illicit gain and involves cooperation in sin and transgression. They must seek lawful sustenance. If they continue in their prohibited work, it is permissible for the two sisters to give them zakat from their wealth to meet their needs.
