What is the ruling on avoiding hosting the mother, and avoiding any meeting between her and the wife, whether in the children's home or the family home, to avoid the recurring problems caused by the mother?

We advise you to supplicate frequently for your mother for guidance and protection from evil, for supplication is among the best acts of righteousness. Your diligent effort in reconciling your mother and your wife is the optimal way to solve the problem, so do not despair. There is no blame upon you for avoiding their gathering in one place to prevent problems. And be keen on being dutiful to your mother in every possible way, through visits, calls, and inquiring about her well-being.
