O you who believe, consume not your goods between you wrongly, unlawfully according to the Law, through usury or usurpation, except it be trading (tijāratan, also read tijāratun), so that the goods be from trade effected, through mutual agreement, through mutual good-will: such [goods] you may consume. And kill not yourselves, by committing what leads towards destruction on account of some affiliation, be it in this world or the Hereafter. Surely God is ever Merciful to you, when He forbids you such things.
