Is a man considered sinful if he divorces his wife because she refused to live in a home away from his mother, especially after the wife rejected living near the mother and demanded distance from her and severing the connection of his daughters with their grandmother and her family, while the mother refuses to live alone fearing harm might befall her?

Some scholars hold that if the husband stipulates to his wife that she live with his parents, and she agrees, then she has no right to demand another dwelling, unless she is harmed, in which case she has the right to demand a separate dwelling.

So, if you have allocated a separate and suitable part of the house for your wife, and she is not subjected to harm therein, then she has no right to request another dwelling.

It is not your wife's right to prevent her daughters from visiting their grandmother, nor to prevent you from frequently visiting your mother.

You should come to an understanding with your wife and explain that she has no right to demand another dwelling as long as she is in a separate dwelling where there is no harm, and that part of good companionship is being kind to your family and helping you to honor your parents. You should be patient, wise, and strive to reconcile between them.

If your wife insists on seeking a divorce, then there is no sin upon you in divorcing her.
