Al-Ghazālī, The Rescuer from Error

Summary

[77] Praise be to God, with whose praise every epistle and treatise begins, and blessings upon Muḥammad, the chosen one, prophet, and messenger, and upon his kin and companions who guide one from error.

You have asked me, my brother in religion, to convey to you the aim and secrets of the sciences, as well as the confusing intricacies of creeds, and to relate what I have endured in extricating truth from the mayhem of factions, with their differing approaches and methods, and how I have ventured to raise myself from the depths of conformity to the heights of insight. You have also asked me to relate, first, what I gleaned from theology; second, what I gathered from the methods of the Instructionists, who hold that truth is apprehended solely by conforming to the instruction of the imām; third, what I criticized of the methods of philosophizing; and finally, what I endorsed of [78] the method of mysticism. You have asked me to convey the nuggets of truth that I uncovered in the midst of my investigation into the doctrines of humanity, what diverted me from the spread of knowledge in Baghdād despite the large number of students, and what led me to resume teaching in Nishapur after a long absence. Therefore, I will hasten to comply with your demand, having determined the sincerity of your request, and will relate this to you, asking God for assistance, support, success, and refuge.
