What is the ruling of Islamic law regarding the dispute between the spouses, the details of which are mentioned, and who is at fault in it? Is it permissible for the husband's mother to cut off ties with her son's wife and her children? And is the children's cutting off ties with their sister—by order of their mother—considered an act of disobedience to parents (Uquq)?

The husband is sinful for abandoning financial support of his wife and children without a valid excuse, and he must repay what she borrowed for their maintenance. He is also sinful for wronging his wife and harboring ill suspicions about her without proof, and he is more obliged to apologize. The mother-in-law's action of ordering her children to shun her son's wife is wrong, and obedience to her in this matter is not obligatory. The children should reconcile between the spouses and between the wife and the mother-in-law.
