﴿ فَإِن لَّمْ تَفْعَلُوا۟ فَأْذَنُوا۟ بِحَرْبٍۢ مِّنَ ٱللَّهِ وَرَسُولِهِۦ ۖ وَإِن تُبْتُمْ فَلَكُمْ رُءُوسُ أَمْوَٰلِكُمْ لَا تَظْلِمُونَ وَلَا تُظْلَمُونَ ﴾

“for if you do it not, then know that you are at war with God and His Apostle. But if you repent, then you shall be entitled to [the return of] your principal: you will do no wrong, and neither will you be wronged.”

But if you do not do what you have been commanded then be warned have knowledge of war from God and His Messenger against you herein is a grave threat for them. When it was revealed they said ‘What power can we have in a war against Him!’ Yet if you repent and forgo it you shall have your principal sums the original amounts not being unjust by charging interest and no injustice being done to you by way of any diminution.
