وَإِن خِفتُم شِقاقَ بَينِهِما فَابعَثوا حَكَمًا مِن أَهلِهِ وَحَكَمًا مِن أَهلِها إِن يُريدا إِصلاحًا يُوَفِّقِ اللَّهُ بَينَهُما ۗ إِنَّ اللَّهَ كانَ عَليمًا خَبيرًا

And if you fear dissension between the two, send an arbitrator from his people and an arbitrator from her people. If they both desire reconciliation, Allah will cause it between them. Indeed, Allah is ever Knowing and Acquainted [with all things].
