What is the optimal course of action towards a mother who requests the return of her only son who is caring for her, while the son desires to care for both his mother and his wife at the same time?

Obeying a mother in her request to live near her son is obligatory if the son is able to do so and fulfilling her request does not cause him harm. The son must obey his mother, live near her, and show her dutifulness, for there is a great reward in that. It is recommended to strive to satisfy the wife so that she may live with the mother. If she does not agree, the son should house her in a separate part of the house if possible, or in a house near his mother so that he can see her and take care of her when needed.
