It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: If you abandon jihad, hold onto the tails of cows, and engage in ‘inah (usurious) transactions, Allah the Exalted will impose such humiliation upon your necks that it will not be removed from you until you return to Allah and to the religion which you were bound to.
