(1) Ibn Rashiq (p. 298) describes it as “a small volume.” It is available in Jami al-Rasaʾil 2/191–401, edited by Muhammad Rashad Salim. (2) Ibn Rashiq (p. 298) says it runs to “about fifty folios,” and again (p. 304) refers to it as “A principle on tawakkul (trust in God) and ikhlas (sincerity), about forty folios.” Are these two separate treatises? In Jamiʿ al-Masaʾil, vol. 6, pp. 3–42, there is a work entitled “A Principle on Sincerity to Allah Most High,” while another piece, “On Clarifying Tawakkul,” is printed in Jami al-Rasaʾil 1/85–100, edited by Dr. Muhammad Rashad Salim. (3) MSS F and K read: “wa-taqdīruhu” (“its implicit sense”). (4) MS F reads: “yuzhirūn” (“they manifest”). (5) Ibn Rashiq (p. 298) estimates it at “about fifty folios.” (6) MSS F and K read: “akbar” (“greater”). (7) Ibn Rashiq lists two works: “A Principle on the Prohibition of samāʿ (music audition), about twenty folios,” and “The Prohibition of Samāʿ,” one volume. Several treatises on samāʿ have been printed in Majmuʿ al-Fatawa 11/557–586 and 587–602, and in Jamiʿ al-Masaʾil, vol. 3, pp. 387–389. (8) Noted by Ibn Rashiq (p. 299).
