Ан-Ниса 4:19

Undoubtedly, the successors of a deceased person have the right to inherit his property. But his widow is not to be treated as a part of the inheritance and exploited as the successors decide. Property is inanimate and therefore without feeling, and, as such is a proper object of inheritance, but human beings have sensate, independent existences, and therefore possess the right to decide their future according to their own choice. If there is any physical or temperamental shortcoming in a woman, it should be tolerated so that she may have the opportunity to use her other natural talents to play her part in the building up of the household. One should overlook the unpleasant aspects of her personality and try to adjust amicably. The secret of the progress and solidarity of any family or society is that its members should ignore the shortcomings and deficiencies of each other and give everyone the chance to exercise his or her abilities. Those who adopt the way of patience and tolerance in this world for the sake of God, are the people who will be granted admission to Paradise in the Hereafter. When one does not like one’s life companion and, rather than be tolerant, decides to separate, it often happens that one exaggerates the shortcomings of the other to justify one’s decision. Allegations are fabricated so that the weaker person should become nervous and leave. Similarly, while severing the marriage bond, trumped up reasons are presented to the other party. But these activities are against the covenant. A covenant is considered sacred by God and whether written or unwritten, it is essentially binding. It applies equally to both parties, leaving them no choice of their own.
