Is it permissible to return to the first wife after divorcing her because of the second wife, knowing that the second wife has been divorced twice before, and the husband desires to reunite the family and alleviate financial burdens, in addition to his concerns about his daughter who does not pray?

It is not advisable to return to the first wife who does not pray, as it was narrated from Ahmad that he feared it would not be permissible for a man to stay with her. He should remain with the second wife who observes her prayers and advise her regarding any duties she neglects and explain to her the danger of disobeying her husband. He should also diligently advise his daughter and remind her of the danger of abandoning prayer.
