Surah 4. An-Nisaa', Ayah 128

 This implies that many husbands and wives are unwilling to give the other their rights.

To protect the woman's economic interests, various rules are prescribed for dower in marriage. But the sanctity of marriage itself is greater than any economic interests. Divorce is, of all things permitted, most hateful to Allah. Therefore if a breach between husband and wife can be prevented by some economic consideration, it is better to make that concession than to imperil the future of the wife, the children, and probably the husband also. Such concessions are permissible, in view of the love of wealth ingrained in unregenerate man, but a recommendation is made that we should practise self-restraint, and do what we can to come to an amicable settlement without any economic sacrifice on the part of the woman.
