What is the ruling on a husband benefiting from certain in-kind items (food, clothes, bags) from his workplace in a charitable organization, sometimes paying an estimated amount for the clothes, and what is the ruling on him accepting expensive gifts from the director of another association he deals with, and does this affect the upbringing of children and marital life?

The fundamental principle is that donations to charitable organizations are designated for those in need, and it is impermissible for your husband to take anything from them unless he is deserving and among the poor, without favoritism or depriving others. As for purchasing goods from the charity at a price lower than their value or without authorization to sell, this is void and a breach of trust. He must return what he took or its equivalent. Gifts to employees are ill-gotten gain (bribe) and forbidden; he must dispose of them by handing them over to the organization or to those in need. As for his spending on you, what you were unaware of regarding its illicit nature is permissible for you. He alone is responsible for his unlawful earnings, and he must repent and return what he took unjustly.
