According to the verses of the Holy Qur'an, we have about twenty-six great sins, many of these sins have been assessed by the Holy Qur'an. God says: whoever pays or takes Riba (Unjustified increment in borrowing or lending money, paid in kind or in money above the amount of loan, as a condition imposed by the lender or voluntarily by the borrower)- whether it a person or a bank. " If you will not give up the unlawful interest which you demand, know that you are in the state of war with God and His Messenger". (AL-BAQARA (THE COW), verse 279). In other word, inform the person who takes or gives Riba that God Almighty with his infinite power and his great messenger are both in state of war with you. Who will be the winner in this war, God Almighty and his messenger or the person or bank who takes or gives Riba.
