وَإِذْ أَخَذْنَا مِيثَٰقَكُمْ لَا تَسْفِكُونَ دِمَآءَكُمْ وَلَا تُخْرِجُونَ أَنفُسَكُم مِّن دِيَٰرِكُمْ ثُمَّ أَقْرَرْتُمْ وَأَنتُمْ تَشْهَدُونَ
And when We made with you a covenant (saying): Shed not the blood of your people nor turn (a party of) your people out of your dwellings. Then ye ratified (Our covenant) and ye were witnesses (thereto).
