And do not consume one another's wealth unjustly or send it [in bribery] to the rulers in order that [they might aid] you [to] consume a portion of the wealth of the people in sin, while you know [it is unlawful].
Do not take each other’s wealth unjustly: robbing it or taking it by force or by cheating, and then making it a legal dispute in order to obtain other’s wealth wrongfully, when you know that Allah has prohibited that. Committing a sin knowingly is the worst of things and has the greatest of punishments.
