Is it permissible to exploit expertise in foreign exchange markets with a margin system (leverage) to speculate on the currencies of countries hostile to Muslims, and to use the profits for charity (sadaqat) and struggle in the way of Allah (jihad fi sabilillah), without taking any personal financial return?
