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 question thee (O Muhammad) with regard to warfare in the sacred month. Say: Warfare therein is a great (transgression), but to turn (men) from the way of Allah, and to disbelieve in Him and in the Inviolable Place of Worship, and to expel His people thence, is a greater with Allah; for persecution is worse than killing. And they will not cease from fighting against you till they have made you renegades from your religion, if they can. And whoso becometh a renegade and dieth in his disbelief: such are they whose works have fallen both in the world and the Hereafter. Such are rightful owners of the Fire: they will abide therein.
