Qur'an 4:35 · An-Nisaa

وَإِنْ خِفْتُمْ شِقَاقَ بَيْنِهِمَا فَٱبْعَثُوا۟ حَكَمًۭا مِّنْ أَهْلِهِۦ وَحَكَمًۭا مِّنْ أَهْلِهَآ إِن يُرِيدَآ إِصْلَٰحًۭا يُوَفِّقِ ٱللَّهُ بَيْنَهُمَآ ۗ إِنَّ ٱللَّهَ كَانَ عَلِيمًا خَبِيرًۭا

(35) 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.
