This verse compares usury with alms in some measures, and says that Allah will deprive usury of all blessings and reduces it to nothing; but He will bless alms- giving with increase, because God loves not the ungrateful sinner who grasps to unlawful wealth through usury. In other word the usurers who have abandoned charity and alms, and have adhered to unlawful incomes, are ungrateful to the bounties and the wealth that God has given them. Instead of beeing thankful, they use their wealth in the wrong way of Satan and Sins, such as corruption and oppression or else. Naturally the good God will never love such a bad servant.
