Is it obligatory to give usurious money to a maternal aunt, and is it permissible to keep it when there is no work and her son is an orphan?

It is not permissible to deposit money in a savings account because it involves usury (riba). Any amount exceeding the principal in this account is considered usurious interest and must be disposed of by spending it on public welfare or giving it to the poor and needy. It is permissible to give it to a poor and needy relative of the account holder, provided it does not exceed their needs. The ruling on usury does not change by depositing the money in a sibling's account. The orphan's money must be preserved and grown by investing it in permissible ventures, or by depositing it in a Sharia-compliant bank, if available.
