Is it considered zihar for a person to say (like my mother) to confirm his words?

Question:
May Allah reward you, Your Eminence, father. The questioner says: It is common among us in the south for an oath-taker to say "like my mother," intending thereby to confirm his words. What is the ruling on that?

Answer:
This is not zihar, this is not zihar, and it is not even an oath. "Like my mother," if his intention is that this thing is forbidden to him like his mother, then this is an oath, meaning there is an expiation for an oath, because it is the prohibition of something lawful. But if he says "like my mother," meaning he is certain just as his mother is certain, then there is nothing wrong with it. Yes.
