Al-Baqarah 2:217 يسالونك عن الشهر الحرام قتال فيه قل قتال فيه كبير وصد عن سبيل الله وكفر به والمسجد الحرام واخراج اهله منه اكبر عند الله والفتنة اكبر من القتل ولا يزالون يقاتلونكم حتى يردوكم عن دينكم ان استطاعوا ومن يرتدد منكم عن دينه فيمت وهو كافر فاولايك حبطت اعمالهم في الدنيا والاخرة واولايك اصحاب النار هم فيها خالدون ٢١٧

They ask you about the Sacred Month, that is, about fighting in it. Say, “Fighting in it is something grave, but it is much more grave, in the sight of Allah, to prevent (people) from the path of Allah, to disbelieve in Him, and in Al-Masjid-ul-Harām, and to expel its people from there, and Fitnah (to create disorder) is more grave than killing.” They will go on fighting you until they turn you away from your faith if they could, while whoever of you turns away from his faith and dies an infidel, such people are those whose deeds will go to waste in this world and in the Hereafter, and they are people of the Fire. They shall be there forever
