Does Ibn al-Qayyim's book "Al-Ruh" (The Spirit) contain violations of sound doctrine and grave-worshipping innovations, especially concerning the affirmation of dead souls' ability to act, and what people see of dead souls and their coming to them, and what did Ibn al-Qayyim intend by citing such texts?

Ibn al-Qayyim's book, "Kitāb al-Rūḥ" (The Book of the Soul), is a beneficial work containing useful knowledge and discussions. However, it includes some less favored opinions where the Imam relied on traditions and dreams for which there is no evidence. This does not detract from the author, as Sheikh Ibn Baz was asked about the book and stated that it is of great benefit, but it contains some less favored aspects, and that a student of knowledge, upon reading it, can distinguish between the preponderant and the less favored.

Ibn al-Qayyim did not assert the ability of souls to intervene (in worldly affairs) as Sufis claim. Rather, he discussed the swiftness of the soul's movement and its transference. The fact that the deceased can hear or perceive does not necessitate the permissibility of supplicating to them or seeking anything from them. He concluded his book by clarifying the concept of Tawhid (definition) (monotheism) and refuting Shirk (definition) (polytheism), stating that it is impermissible to attribute any of the Creator's exclusive attributes to a creature.
