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. but if you repent you will have your capital without being wronged or having done wrong to others.
فإن لم تفعلوا فأذنوا بحرب من الله ورسوله وإن تبتم فلكم رءوس أموالكم لا تظلمون ولا تظلمون
