﴿ وَإِذْ أَخَذْنَا مِيثَٰقَكُمْ لَا تَسْفِكُونَ دِمَآءَكُمْ وَلَا تُخْرِجُونَ أَنفُسَكُم مِّن دِيَٰرِكُمْ ثُمَّ أَقْرَرْتُمْ وَأَنتُمْ تَشْهَدُونَ ﴾

“And lo! We accepted your solemn pledge that you would not shed one another's blood, and would not drive one another from your homelands - whereupon you acknowledged it; and thereto you bear witness [even now].”

(And when We made with you a covenant) in the Book: (shed not the blood of your people) do not kill one another (nor turn your people) i.e. one another (out of your dwellings) from your homes, meaning: the Banu Qurayzah and Banu'l-Nadir. (Then ye ratified (Our covenant)) you agreed to it (and ye were witnesses (thereto)) while knowing what you were doing.
