2:192But if they cease, then God is Forgiving and Merciful.

2:193And fight them until there is no oppression, and worship becomes devoted to God alone. But if they cease, then let there be no hostility except against the oppressors.

2:217They ask you about fighting during the Holy Month. Say, “Fighting during it is deplorable; but to bar others from God’s path, and to disbelieve in Him, and to prevent access to the Holy Mosque, and to expel its people from it, are more deplorable with God. And persecution is more serious than killing. They will not cease to fight you until they turn you back from your religion, if they can. Whoever among you turns back from his religion, and dies a disbeliever—those are they whose works will come to nothing, in this life, and in the Hereafter. Those are the inmates of the Fire, abiding in it forever.
