Sanctity of Life and Blood

وَإِذْ أَخَذْنَا مِيثَـٰقَكُمْ لَا تَسْفِكُونَ دِمَآءَكُمْ وَلَا تُخْرِجُونَ أَنفُسَكُم مِّن دِيَـٰرِكُمْ ثُمَّ أَقْرَرْتُمْ وَأَنتُمْ تَشْهَدُونَ

And [recall] when We took your covenant, [saying], "Do not shed your [i.e., each other's] blood or evict one another from your homes." Then you acknowledged [this] while you were witnessing.
