What can we say to a quarreling couple?
Chapter 2

َسْأَلُونَكَ عَنِ الأَنفَالِ قُلِ الأَنفَالُ لِلّهِ وَالرَّسُولِ فَاتَّقُواْ اللّهَ وَأَصْلِحُواْ ذَاتَ بِيْنِكُمْ وَأَطِيعُواْ اللّهَ وَرَسُولَهُ إِن كُنتُم مُّؤْمِنِينَ (سورۃ الانفال, آية 1)

They ask thee concerning (things taken as) spoils of war. Say: "(Such) spoils are at the disposal of Allah and the Messenger: so fear Allah, and keep straight the relations between yourselves: obey Allah and His Messenger, if ye do believe." (Surah 8, Verse 1)

The teacher noticed that Lama, an eighth-grade student, had been behaving strangely for some time. She didn't concentrate in class, when she was addressed she did not answer and she appeared to be in a world of her own as if she were living in a bubble. The teacher sent Lama to the counselor and Lama told her that her parents quarreled all the time. All the past week there had been shouting and they had even come to blows. At night, she said, she  often awoke with a start in fear, covered in cold sweat. She was afraid that her parents might divorce.

The counselor scheduled a meeting with Lama's parents. She told them how Lama was suffering because of their incessant quarreling and how their tense relationship was affecting both her studies and her relations with her friends. She advised the parents to try to solve their problems quietly and without violence and to foster understanding for the sake of their children. "You must maintain family unity as the Quran commands us," she said. She opened the Quran at Surah 8, Verse 1, and read out to them: "So fear Allah, and keep straight the relations between yourselves."  The parents realized that it was the will of Allah that they make peace and decided to make an effort to stop quarreling for the sake of the family.

Explanation: In every culture there are disputes between couples and it is not always easy and simple to solve them. In non-religious societies, divorce is rife because each of the partners is concerned with his or her own emotions; when they quarrel bitterly there is no unifying authority which can help them solve their problem. But in this case, the Quran imposes its authority and commands the couple to make peace. Lama's parents are believers who are in awe of Allah and so they obey the command and make peace. When Allah commands, all mutual recriminations and incessant quarreling  must cease. Now, when each is responsible for his or her own action and ready to forgive the other and act compassionately, the couple can open a new page and improve their relationship. In other words, the Divine authority elevates the couple from a state of mutual recriminations to one of mutual responsibility.
