Belivei it or not, Ibn Taimiyya was himself a Sufi of the Qadiri Order! But he accepted Tasawwuf on the condition that it follows shari'ah, which no Sufi order object. In fact Shari'ah is like a boat, Tariqa is like an ocean and Haqiqat is like the precious pearl. Who ever aspires after the pearl must (definitely) embark on the boat and then dive into the ocean. Logically nobody reaches the pearl without having to sail on the boat. In this book you will find many more shocking realities about Ibn Taimiyya that contradict the very foundation of the anti-sufi movements.
In fact Ibn Taimiyya says: "The miracles of saints are absolutely true and correcct, by the acceptance of all Muslim scholars. And the Qur'an has pointed to it in different places, and the hadith of the Prophet, peace be upon him, have mentioned it, and who ever denies the miraculous power of saints are only people who are innovators and their followers."
