An-Nisa · 4:35

35. If you fear that a disagreement between the two of them is leading to aggression and incompatibility, then send a just man from the family of the husband, and a just man from the family of the wife to judge what the benefits of them separating or staying together might be. Staying together is preferable and better. If the two judges want this, using the best methods to get them back together, then Allah will make them come to an understanding, and the argument between them will be resolved. Allah is Knowing. Nothing about His creatures is hidden from Him, and He is Aware of what they hide in their hearts.
