This is the 2012 reprint of the original 1961 work by Dr Muḥammad Zubayr Ṣiddīqī, Sir Asutosh Professor of Islamic Culture, Calcutta University.
The book was later edited by Abdal Hakim Murad (Timothy J. Winter) and published under the title Ḥadīth Literature: Its Origin, Development and Special Features by Islamic Texts Society. The edition by Islamic Texts Society no longer reflects the original work of the author, since many significant changes have been made to the text and the concluding paragraph by the author at the end has been left out of the book also.
Fortunately, Goodword Books, New Delhi, has published a reprint of the original 1961 edition of the book.
“To conclude, I may add that there is enough material available for the compilation of a standard collection of completely authentic traditions out of the already generally accepted compilations of them. I have reached this conclusion after examining each tradition contained in them according to the principles already laid down by the Muslim Traditionists, as well as according to those which may be prescribed by modern literary critics. It is, of course, a tremendous task; but, certainly, it can be achieved with the combined efforts of such Muslim scholars and modern Orientalists as may be interested in the subject.” [page 222]
