4:21
وَكَيْفَ تَأْخُذُونَهُۥ وَقَدْ أَفْضَىٰ بَعْضُكُمْ إِلَىٰ بَعْضٍ وَأَخَذْنَ مِنكُم مِّيثَـٰقًا غَلِيظًا
wakayfa takhudhūnahu waqad afḍā baʿḍukum ilā baʿḍin wa-akhadhna minkum mīthāqan ghalīẓan
How could you take it when this is unjust and a blatant sin? How could you take it when you have lain with each other and they have taken a solemn pledge from you?
And how could you take it (back) while you have gone in unto each other, and they have taken from you a firm and strong covenant?
