Do the dead know the conditions and deeds of the living?

Question:
This man says that he found in Ibn al-Qayyim’s book *The Spirit* that the dead know the conditions of the living, or the deeds of the living. We say that this is part of the knowledge of the unseen, which no one knows except Allah. The conditions of the barzakh (the interval between death and resurrection) and the conditions of the grave are matters of the unseen; we do not say anything about them except based on evidence from the Book and the Sunnah.

Answer:
If evidence comes that the dead know the conditions or the deeds of the living, we say that this is established. But if no evidence is reported, we do not say anything except what the evidence indicates, whether Ibn al-Qayyim or anyone else said it; evidence is necessary. Yes.
