If one of them swears an oath upon a person to do something, and that person does not do it, is the expiation obligatory upon him, and does the one upon whom the oath was sworn commit a sin?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, if a person swears by Allah upon a created being to do a deed for him, and that person refuses to do the deed, does he commit a sin? And is the expiation of an oath obligatory upon the one who swore?

The Shaykh:
There is no doubt that the expiation of an oath is obligatory upon the one who swore if he swore upon another to do something and that person did not do it. The expiation of an oath is obligatory upon him because he broke his oath in that. Yes. And what is the question?

The questioner:
Is the expiation of an oath obligatory upon him?

The Shaykh:
We have established that the expiation of his oath is obligatory upon him. And the second thing, I do not know what is in the question.

The questioner:
If a person swears by Allah upon the one upon whom the oath was sworn, and he refuses, does the one who did not do it commit a sin?

The Shaykh:
The one upon whom the oath was sworn commits a sin if he is able to do it and does not do it. This is because fulfilling his oath is from the Sunnah, or from the rights of your brother that you have. Yes, fulfilling the oath of the one who swore is from the rights of a created being upon a created being. Yes.
