Is it permissible to give the 15% allocated for public welfare from the profits of halaal shares deposited in usurious banks to relatives, such as the mother or siblings, for their benefit?

"Investing in companies is permissible if their buying and selling activities involve lawful materials, and they do not deal with usury or other forbidden transactions. If either of these two conditions is not met, then the investment is prohibited. If an investor doubts the permissibility of a certain company, it is safer for them not to invest, acting upon the words of the Prophet, peace and blessings be upon him: 'Leave that which makes you doubt for that which does not make you doubt,' and his saying: 'Whoever protects himself from doubtful matters has indeed cleared himself for his religion and his honor.' As for the money resulting from a prohibited investment, the investor must dispose of it by spending it on various charitable causes, provided that they do not benefit from it personally. Thus, it should not be used to fulfill an obligation or ward off harm from themselves."
