Hajj for one who has lost his memory and his obligation to perform acts of worship

The Shaykh:
It is sufficient for me to stop here. As a note, next week there will be nothing, because I have a trip, if Allah wills, until next Saturday, excluding the coming Saturday. Yes.

The questioner:
He says: Honorable Shaykh, may Allah grant you success, will there be a lesson on the book of Tawhid (the oneness of Allah) tomorrow, Wednesday, in the mosque of Shaykh al-Islam?

The Shaykh:
I have no news about this. I have no news about it, and there is an announcement. Yes.

The questioner:
I do not have it.

The Shaykh:
Yes, yes, yes.

The questioner:
I say: Honorable Shaykh, may Allah grant you success. One who has lost his memory and has not performed Hajj, does someone perform Hajj on his behalf? And is he required to perform the obligatory acts of worship?

The Shaykh:
No, this person is not accountable. If he has lost his memory, he is not accountable. If his intellect is gone, he is not accountable. Yes.
