What should a husband do who told his wife "you are divorced" unconsciously after the wife's mother asked them to get rid of her?

If a man says to his wife, "You are divorced," then the divorce takes effect, because it is an explicit pronouncement that does not require intention.

- If it was the first or second divorce, he may reconcile with his wife as long as she is within her waiting period (iddah). If she has exited her waiting period, she cannot return to him except with a new contract, mahr (dowry), and wali (guardian).

- If it was the third divorce, the wife becomes irrevocably divorced (baynunah kubra), and she is not lawful for her first husband until she marries another man and he consummates the marriage with her in a valid manner.
