What is the book "Mukashafat al-Qulub fi Hadrat Allam al-Ghuyub" and is it considered one of the books of Sufi innovations (bid'ah)?

The book "Mukashafat al-Qulub fi Hadrat Allam al-Ghuyub" (Unveiling of Hearts in the Presence of the Knower of the Unseen) is falsely attributed to Imam Abu Hamid al-Ghazali. Researchers have cited several reasons for this, including:

1. The author's statement at the beginning of the book: "Named Mukashafat al-Qulub, bringing one closer to the Knower of the Unseen, attributed to Sheikh al-Ghazali." It is inconceivable that al-Ghazali would say this about himself. 2. The author of the book mentions al-Qurtubi, who died in 671 AH, while al-Ghazali died in 505 AH. How could he transmit from him? 3. The writer quotes in several places from the book "Zahr al-Riyad wa Shifa' al-Qulub al-Mirad" by al-Qastallani, who died in 923 AH. 4. The book includes a large number of embellished anecdotes and lessons from al-Ghazali's books and others, which indicates the absence of al-Ghazali's intellectual rigor and independent writing style.

Researchers have not found any statements from scholars evaluating the book or any critical studies of its content.
