(1) Ibn al-Qayyim mentions it in his poem al-Nuniyyah, saying: “So too ‘The Foundation’—its Refutation has become a marvel to every god-fearing scholar.” (2) Copy F adds “and the Qadariyya,” whereas T reads “the Shiʿa.” The author himself states the title inside the work: “For this reason this book is entitled Minhaj Ahl al-Sunnah al-Nabawiyyah fi Naqd Kalam al-Shiʿa wal-Qadariyya” (Minhaj, 2/199). (3) The book was published in nine volumes by Imam University (Riyadh), edited by Dr. Muhammad Rashad Salim. (4) The adversary is Hasan (or Husayn) ibn Yusuf ibn al-Mutahhar al-Hilli al-‘Iraqi, Abu Mansur (d. 726/1326), a prolific Shiʿi author. The work refuted is Minhaj al-Karama—also known as al-Isti­qama—fi Maʿrifat (or Ithbat) al-Imama. See al-Bidaya wa-l-Nihaya 18:271–72 and al-Durrar al-Kamina 2:71–72. (5) Copies B and Q read: “and their misguidance.” (6) This phrase is absent from B and Q. (7) Ibn Rashiq (p. 294) also says the work comprised four volumes, while others say six, as Ibn al-Qayyim versified in al-Nuniyyah: “Likewise his Egyptian replies— six copious tomes were set down.” The target of the refutation was Qadi Shams al-Din Ahmad ibn Ibrahim al-Saruji al-Hanafi (d. 710/1310), whom Ibn Taymiyyah called “the best of the opposing judges” (Bayan Talbis al-Jahmiyyah, 1:6). His biography appears in al-Jawahir al-Mudiyyah 1:123 and al-Bidaya wa-l-Nihaya 18:107. Two fragments of Ibn Taymiyyah’s reply have been printed in a slim volume within this series (Athar Shaykh al-Islam Ibn Taymiyyah), edited by our colleague, the researcher Shaykh Muhammad ‘Aziz Shams.
