What is your opinion of the book "Al-Fath ar-Rabbani wa al-Fayd ar-Rahmani" by Sheikh Abd al-Qadir al-Jilani, and has it received criticism from the scholars of Ahl as-Sunnah wa al-Jama'ah?

The book contains admonitions and advice on spiritual refinement, purification of souls, and traversing the path to Allah. It is presented in 62 sessions, printed in 375 pages. Overall, it is beneficial, but it is not devoid of Sufi terms and meanings that require interpretation. Its status is similar to that of its author, about whom Al-Dhahabi said in "Siyar A'lam al-Nubala'": "Shaykh Abd al-Qadir is of great stature, but there are reservations regarding some of his statements and claims." There is no record of an evaluation of the book by earlier scholars.
