What are the supplications and solutions that can end tension and distress in the home and help the father think soundly and not succumb to the wishes of his sister, who seeks to destroy homes, especially since the mother has become depressed?

There are prophetic supplications and remembrances for repelling worry and sorrow. The father is advised gently and kindly to treat his wife and children well, listen to good words from his sister, and abandon evil. The paternal aunt is also advised to fear Allah and not stir up problems. The advice should be given gently, accompanied by abundant supplication, and seeking the help of influential figures for reconciliation. It is the wife's right to have independent accommodation separate from her husband's relatives, and your mother can refuse the paternal aunt living with you to avoid awkwardness and protect against her harm, while exercising wisdom to avert greater problems.
