2:216Fighting is ordained for you, even though you dislike it. But it may be that you dislike something while it is good for you, and it may be that you like something while it is bad for you. God knows, and you do not know.

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.

2:246Have you not considered the notables of the Children of Israel after Moses? When they said to a prophet of theirs, “Appoint a king for us, and we will fight in the cause of God.” He said, “Is it possible that, if fighting was ordained for you, you would not fight?” They said, “Why would we not fight in the cause of God, when we were driven out of our homes, along with our children?” But when fighting was ordained for them, they turned away, except for a few of them. But God is aware of the wrongdoers.
