What is the ruling on taking inherited money from the deceased father from social insurance, given the uncertainty about the legality of its source, as it is commercial insurance and placed in usurious banks?

Social security or pension is a matter of scholarly disagreement. The majority of scholars deem it permissible if the state administers it for mutual support, not for profit. It is not considered a financial exchange similar to prohibited commercial insurance. Rather, it is assistance for specific groups due to old age, illness, or accidents. The aforementioned amount falls under the same ruling, but the problem lies in keeping it in an interest-bearing bank. The resulting interest must be disposed of by spending it on charitable causes. The poor may take from it what they need, not because it is their right. If the origin of the amount is unknown, one can inquire about it at the social security institution.
