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 month¹ - about fighting therein. Say, "Fighting therein is great [sin], but averting [people] from the way of Allāh and disbelief in Him and [preventing access to] al-Masjid al-Ḥarām and the expulsion of its people therefrom are greater [evil] in the sight of Allāh. And fitnah² is greater than killing." And they will continue to fight you until they turn you back from your religion if they are able. And whoever of you reverts from his religion [to disbelief] and dies while he is a disbeliever - for those, their deeds have become worthless in this world and the Hereafter, and those are the companions of the Fire; they will abide therein eternally.
