One of the campaigns undertakes an investment work in the funds of proxy Hajj, so that the earnings will go to charitable projects that support religion. The funds are collected with certain amounts during which they agree with their payers who want a proxy Hajj to provide them with proxy pilgrims, and they actually agree with people with a lesser amount and the profits taken from that are spent in charitable works. Is that permissible?
