6. A single close-quote mark has been inserted after "vouchsafed to him" (Page 127). 7. _karāmat_ (Page 129) has been changed to _karāmāt_. 8. The line beginning "Then he quotes" (Page 160) has had its indentation reduced, as it is part of the main text and not (as printed) part of the preceding quotation. 9. Index: The character ʿ has been added in the words Abu ’l-Khayr al-Aqtaʿ, ʿAlāʾuddīn, _muʿjizat_, Muʿtazilites, and Rābiʿa. 10. Apparent inconsistencies in whether hyphens occur in the word pairs "well known", "passed away", and "above mentioned" are judged to be due to differences in sense, and no amendments have been made.
