Is it permissible to give interest-based earnings acquired from banks to married daughters who are in difficult financial circumstances?

Depositing money in the bank with interest is unlawful (haram (definition)) according to Islamic law, unless there is a fear of the money being stolen and no means of preserving it except by depositing it in a current account without interest; for necessities permit prohibitions. Whoever has fallen into usury must repent and dispose of the unlawful interest by spending it on charitable causes, and it is not permissible for him to benefit from it. There is no harm in giving these interests to your married daughters if they are in need of money, as their financial support is not obligatory upon you.
