: They ask you concerning fighting in the Sacred Months (i.e. 1st, 7th, 11th and 12th months of the Islamic calendar). Say, "Fighting therein is a great (transgression) but a greater (transgression) with Allah is to prevent mankind from following the Way of Allah, to disbelieve in Him, to prevent access to Al-Masjid-al-Haram (at Makkah), and to drive out its inhabitants, and Al-Fitnah is worse than killing. And they will never cease fighting you until they turn you back from your religion (Islamic Monotheism) if they can. And whosoever of you turns back from his religion and dies as a disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will be the dwellers of the Fire. They will abide therein forever.
