They ask you about fighting in the sacred month. Say, "To fight [in a sacred month] is a grave matter; but barring people from the path of God, to deny Him, and expelling people from the Sacred Mosque are far graver in His sight; and persecution is worse than killing." They will not stop fighting you until they make you renounce your faith, if they can. Whoever of you turns back from his faith and dies as a denier of the truth will have his deeds come to nothing in this world and the Hereafter, and he will be an inhabitant of the Fire, to abide therein forever.
