4 : 35
وَإِنۡ خِفۡتُمۡ شِقَاقَ بَيۡنِهِمَا فَٱبۡعَثُواْ حَكَمٗا مِّنۡ أَهۡلِهِۦ وَحَكَمٗا مِّنۡ أَهۡلِهَآ إِن يُرِيدَآ إِصۡلَٰحٗا يُوَفِّقِ ٱللَّهُ بَيۡنَهُمَآۗ إِنَّ ٱللَّهَ كَانَ عَلِيمًا خَبِيرٗا
If you fear a breach between them, appoint an arbitrator from his family and another from hers. If they both want reconciliation, Allah will bring harmony between them. Indeed, Allah is All-Knowing, All-Aware.
