كَيْفَ وَإِن يَظْهَرُوا عَلَيْكُمْ لَا يَرْقُبُوا فِيكُمْ إِلًّا وَلَا ذِمَّةً ۚ يُرْضُونَكُم بِأَفْوَاهِهِمْ وَتَأْبَىٰ قُلُوبُهُمْ وَأَكْثَرُهُمْ فَاسِقُونَ (8)
(9:8) But how can a treaty be regarded as abiding with the other mushriks? Since if they get power over you, they will not respect ties of kindred with you nor honour any treaty obligations. They try to conciliate you with their tongues, while their hearts are averse to their tongues, *10 for most of them are evil-doers. *11
*10) That is, "Though outwardly they negotiated for peace treaties, they cherished evil intentions in their hearts, and waited for an opportune moment to break them. And this was borne by later experiences."
*11) They were evil-doers because they had no sense of moral responsibilities nor did they hesitate to break moral limits.
