The oath-taker's statement: "It is upon me like my mother"

The questioner:
Your Eminence, father. The questioner says: Some of the common people among us, when they take an oath, say, "It is upon me like my mother." Is this considered [zihar]?

The Shaykh:
Yes.

The questioner:
May Allah reward you. He says: Some of the common people among us, when they take an oath, say, "It is upon me like my mother."

The Shaykh:
What is it that is upon him like his mother? Food? That is, if he says, "This food is upon me like my mother," then he owes an expiation for it, because its meaning is that the food is forbidden.
