أَوَكُلَّمَا عَـٰهَدُوا۟ عَهْدًا نَّبَذَهُۥ فَرِيقٌ مِّنْهُم ۚ بَلْ أَكْثَرُهُمْ لَا يُؤْمِنُونَ
awakullamā ʿāhadū ʿahdan nabadhahu farīqun min'hum bal aktharuhum lā yu'minūna
Is it not [true] that every time they took a covenant a party of them threw it away? But, [in fact], most of them do not believe.
