4:21
وَكَيْفَ تَأْخُذُونَهُۥ وَقَدْ أَفْضَىٰ بَعْضُكُمْ إِلَىٰ بَعْضٍۢ وَأَخَذْنَ مِنكُم مِّيثَٰقًا غَلِيظًۭا
Wa kaifa taakhuzoonahoo wa qad afdaa ba'dukum ilaa ba'dinw wa akhazna minkum meesaaqan ghaleezaa
And how can you take it when one of you has already gone in to the other and they have made with you a firm covenant?
