What is required of the one who said to his wife in a state of anger, "You are like my mother," and then reconciled with her afterward

The questioner:
Two years ago, I quarreled with my wife, and I said to her several times while in a state of anger, "You are like my mother." Three days later, we reconciled, and no one knew about our quarrel at all, except Allah (Glorified and Exalted is He). Do we have a sin in that, or an expiation?

The Shaykh:
You must repent to Allah; because zihar is an abomination of speech and a lie, as Allah (Glorified and Exalted is He) said, and it is indeed a great sin . Therefore, zihar is not permissible. Allah (Glorified and Exalted is He) permitted the wife and did not forbid her, so He made likening her to your mother or your sister among the abominations. So you must repent to Allah (Glorified and Exalted is He) from that, and you must pay the expiation for zihar, which is freeing a believing slave. If you cannot do that, then fasting for two consecutive months. If you cannot do that, then feeding sixty poor people before you touch her.
This is the obligatory ruling, based on His saying to . So you must free a slave if you can find one. If that is not feasible, you must fast for two consecutive months. If you are unable to do that, you must feed sixty poor people, which is thirty sa' (a dry measure of about 3 kg) of the local staple food, with each person receiving half a sa' of the local staple food, which is approximately one and a half kilograms of rice, dates, wheat, or something similar to the local staple food, before you have any sexual intercourse with her, along with repentance to Allah, seeking His forgiveness, and regret for what happened on your part. And Allah, Mighty and Majestic, accepts the repentance of those who repent if they are sincere in their repentance. Yes.

The questioner:
And regarding what happened from him before he knew of this ruling?

The Shaykh:
He must repent to Allah and refrain and stop until he pays this expiation. Yes.
