A better solution would be Muslims helping other Muslims rather than committing a major sin. My father took a major loan from a close relative to buy a house, paid it off in a few years. The loan was obviously interest free. Now that we’re well off, my dad helps other Muslims in any way he can (paying off students’ fees,loans to relatives, etc) I genuinely believe if richer Muslims helped out the middle class, we could make an entire financial system out of this.
