Is it permissible for a brother to spend from ill-gotten wealth on the education of his brother and mother, knowing that there is no other provider for the family, and would this result in the brother dropping out of university?

It is possible that the work is in a place where there are objectionable things, and this does not make the money unlawful, or that the work itself is unlawful, in which case the salary would be unlawful.

If the earning is unlawful, scholars have differed whether its unlawfulness is restricted to the earner or extends to others.

According to the view that the money is unlawful, it is permissible for the mother to take from it for her own expenses if she has no other lawful money.

It is permissible for the brother to take from it according to his need if he is poor and unable to earn, or if his expenditure is obligatory upon him.

If the brother's money is mixed (containing both lawful and unlawful elements), then it is permissible to deal with him concerning his money.
