How sound are the claims and hadith mentioned in this video?

It has been previously explained that the messages attributed to the servant of the Prophetic Chamber are deceptive, and Sheikh Ibn Baz and the Permanent Committee have affirmed their falsehood. Attributing them to Sheikh Ahmad—who died a long time ago and whose family denied their attribution to him—is either a fabrication or a delusion. What indicates their falsity is: their containing unseen matters known only to Allah, such as the number of those who died outside of Islam and the specific recompense for deeds or the threat for abandoning them, and the claim that the Prophet, peace be upon him, said he was ashamed of people's actions, in addition to the assertion that not believing in them is disbelief. All of this contradicts reality and Islamic Sharia (definition).
