Riba (interest, usury) is primarily an economic issue in view of the fact that all religions and mythologies have prohibited, restricted, discouraged, disliked, or degraded Riba in one way or the other since the inception of human interaction. All three major revealed (Ilhami) religions i.e., Islam, Christianity, and Judaism have strongly condemned and prohibited Riba in its original versions. Later, the clerics of Jews and Christian Church abandoned the prohibition of Riba (interest, usury) that led the mankind into the economic anarchy of the present era.
