Qur'an 4:35

وَإِنْ خِفْتُمْ شِقَاقَ بَيْنِهِمَا فَٱبْعَثُوا۟ حَكَمًا مِّنْ أَهْلِهِۦ وَحَكَمًا مِّنْ أَهْلِهَآ إِن يُرِيدَآ إِصْلَـٰحًا يُوَفِّقِ ٱللَّهُ بَيْنَهُمَآ ۗ إِنَّ ٱللَّهَ كَانَ عَلِيمًا خَبِيرًا

“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, Allāh will cause it between them. Indeed, Allāh is ever Knowing and Aware.”
