﴿ ٱلَّذِينَ عَٰهَدتَّ مِنْهُمْ ثُمَّ يَنقُضُونَ عَهْدَهُمْ فِى كُلِّ مَرَّةٍۢ وَهُمْ لَا يَتَّقُونَ ﴾

“AS FOR THOSE with whom thou hast made a covenant, and who thereupon break their covenant on every occasion, not being conscious of God-”

Then Allah explained who these are, saying: (Those of them with whom thou madest a treaty) the Banu Qurayzah, (and, then at every opportunity they break their treaty, and they keep not duty (to Allah)) they do not ward off breaking their treaties.
