What is the ruling on a person in ihram who covered his head while ignorant of the ruling?

The questioner:
He says: Honorable Shaykh, may Allah grant you success. A person in 'Umrah was told by another that covering the head in ihram is not permissible, so this pilgrim covered his head, then removed the covering. He says, "I did not know about this statement, and I had not heard of it, since he was ignorant of the ruling."

The Shaykh:
What do you say? What do you say?

The questioner:
A person in 'Umrah was told by another that covering the head in ihram...

The Shaykh:
And he was covering his head, meaning.

The questioner:
Yes. That covering the head in ihram is not permissible, so he placed the ihram covering on his head, then removed it, and said, "I did not know about this statement, and I had not heard of it, and he was ignorant of the ruling." So what is obligatory upon him?

The Shaykh:
Meaning, has he never performed Hajj or 'Umrah? We see all the pilgrims with their heads uncovered. This statement is either a misrepresentation, or he has never performed Hajj or 'Umrah and is ignorant of this matter. The ignorant person is taught and it is explained to him that this is not permissible. The Messenger (peace and blessings be upon him) said regarding the one whose camel strayed, "Do not cover his head," even though he was dead. He said, "Do not cover his head, for he will be raised on the Day of Resurrection while reciting the talbiyah." This indicates that the one in ihram does not cover his head. And some of the Companions said, "I have been commanded to do so for the one for whom I entered ihram." Yes.
