Divorce
If you fear discord between them, appoint an arbitrator from his family and an arbitrator from hers. If they seek reconciliation, Allah will bring harmony between them.
4:35And if ye fear a breach between them twain (the man and wife), appoint an arbiter from his folk and an arbiter from her folk. If they desire amendment Allah will make them of one mind. Lo! Allah is ever Knower, Aware.
