Is there a difference between saying, “I ask you by Allah,” and “I ask you by the Face of Allah”?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, is there a difference between saying, “I ask you by Allah,” and “I ask you by the Face of Allah”?

The Shaykh:
“I ask you by Allah” or it is all the same, because “Allah” is one of the names of Allah (Mighty and Majestic), and “the Face of Allah” is one of His attributes. So “Allah” is one of the names of Allah, and “the Face of Allah” is one of the essential attributes of Allah. Both are correct. Yes.

The questioner:
We say: Honorable Shaykh, may Allah grant you success.

The Shaykh:
That this is asking by the name of Allah, and this asking is by an attribute, so there is a difference between the name and the attribute. Yes.
