Al Baqarah Ayah 217

يَسْــَٔلُونَكَ عَنِ ٱلشَّهْرِ ٱلْحَرَامِ قِتَالٍ فِيهِ‌ۖ قُلْ قِتَالٌ فِيهِ كَبِيرٌ‌ۖ وَصَدٌّ عَن سَبِيلِ ٱللَّهِ وَكُفْرُۢ بِهِۦ وَٱلْمَسْجِدِ ٱلْحَرَامِ وَإِخْرَاجُ أَهْلِهِۦ مِنْهُ أَكْبَرُ عِندَ ٱللَّهِ‌ۚ وَٱلْفِتْنَةُ أَكْبَرُ مِنَ ٱلْقَتْلِ‌ۗ وَلَا يَزَالُونَ يُقَـٰتِلُونَكُمْ حَتَّىٰ يَرُدُّوكُمْ عَن دِينِكُمْ إِنِ ٱسْتَطَـٰعُواْ‌ۚ وَمَن يَرْتَدِدْ مِنكُمْ عَن دِينِهِۦ فَيَمُتْ وَهُوَ كَافِرٌ فَأُوْلَـٰٓئِكَ حَبِطَتْ أَعْمَـٰلُهُمْ فِى ٱلدُّنْيَا وَٱلْأَخِرَةِ‌ۖ وَأُوْلَـٰٓئِكَ أَصْحَـٰبُ ٱلنَّارِ‌ۖ هُمْ فِيهَا خَـٰلِدُونَ ٢١٧ They ask you ?O Prophet? about fighting in the sacred months. Say, “Fighting during these months is a great sin. But hindering ?others? from the Path of Allah, rejecting Him, and expelling the worshippers from the Sacred Mosque is ?a? greater ?sin? in the sight of Allah. For persecution is far worse than killing. And they will not stop fighting you until they turn you away from your faith—if they can. And whoever among you renounces their own faith and dies a disbeliever, their deeds will become void in this life and in the Hereafter. It is they who will be the residents of the Fire. They will be there forever.”
