Is it permissible to benefit from the returns of the blood money deposited by the uncle in the bank as investment certificates, knowing that the original amount was small and became large after 20 years, and that its owner wishes to complete his marriage and his sister's marriage?

The amount exceeding ten thousand Egyptian pounds, which the uncle invested in a forbidden (usurious) manner, must be disposed of by giving it to the poor and needy, not as charity, but to get rid of ill-gotten gains. This is because the Prophet, peace and blessings be upon him, cursed the one who consumes Riba, the one who feeds it, its scribe, and its two witnesses. He also mentioned that the easiest of its doors is like a man marrying his own mother, and that one dirham of Riba is worse in the sight of Allah than thirty-six acts of fornication.
