279. "but if you do (it) not, then be you apprised for war from allah and his apostle, and if you repent, you shall have your capital; (thus) deal you not unjustly (with others), nor you be dealt with unjustly." commentary: in islam, neither usury and taking undue gains are allowed nor can the property of people be confiscated unilaterally. in some governmental regulations, ownership is abrogated and all properties are forcefully taken from their possessors. in some other ones exploitation, devouring other's rights, and usury, in any form, is free. explanations: 1. usurer is a fighter against allah. any usurer would know that, in this battlefield, he (who is a feeble and contemptible mortal) is on one side, and allah, the almighty, is on the other side. " but if you do (it) not, then be you apprised for war from allah and his apostle, ..." 2. since usurer is a fighter against allah, it is to the islamic government, as a duty, to take action against usurers. 3. the right of usurer is to be content with only the capital, without any interest. "... you shall have your capital ..." 4. both being oppressor and oppressive are condemmed. neither accept oppresion nor be an oppressor. "... (thus) deal you not unjustly (with others) nor you be dealt with unjustly." 5. beware not to spare the principle of ownership of people for rescuing the deprived.
