if you fear a breach between the two appoint an arbitrator from his people and an arbitrator from her people. if they both want to set things right allah will bring about reconciliation between them. allah knows all is well aware of everything.
وإن خفتم شقاق بينهما فابعثوا حكما من أهله وحكما من أهلها إن يريدا إصلاحا يوفق الله بينهما إن الله كان عليما خبيرا
