At-Tawbah 9:8

كَيۡفَ وَإِن يَظۡهَرُواْ عَلَيۡكُمۡ لَا يَرۡقُبُواْ فِيكُمۡ إِلّٗا وَلَا ذِمَّةٗۚ يُرۡضُونَكُم بِأَفۡوَٰهِهِمۡ وَتَأۡبَىٰ قُلُوبُهُمۡ وَأَكۡثَرُهُمۡ فَٰسِقُونَ 8

How [can there be a treaty] while, if they gain dominance over you, they do not observe concerning you any pact of kinship or covenant of protection? They satisfy you with their mouths, but their hearts refuse [compliance], and most of them are defiantly disobedient
