[ir123]

your answer really doesn't make sense to me, can you explain it a bit more?

https://en.wikipedia.org/wiki/Riba

> While Muslims agree that riba is prohibited, not all agree on what precisely it is.[2][3] It is often used as an Islamic term for interest charged on loans,[Note 1] and the belief this is based on — that there is a consensus among Muslims that all loan/bank interest is riba — forms the basis of a $2 trillion Islamic banking industry

This is enough to negate what you said here:

>it does not. there is absolutely no basis for "islam forbits interest".

Could you explain what you mean here?

>the problem didn't exist till then so someone just literally invented it and then sold a solution

What problem didn't exist and what was invented and what was the solution?
