(15) And if two parties of the believers quarrel, make peace between them; but if one of them acts wrongfully towards the other, fight that which acts wrongfully until it returns to Allah's command; then if it returns, make peace between them with justice and act equitably; surely Allah loves those who act equitably.

(16) That is because they acted in opposition to Allah and His Apostle, and whoever acts in opposition to Allah, then surely Allah is severe in retributing (evil).
