The book is the English version of Mujtaba Akhir Zamani written by Sultan-ul-Ashiqeen Hazrat Sakhi Sultan Mohammad Najib-ur-Rehman. It is a record of the authentic biographies of The Spiritual Guides of Sarwari Qadri Order.

The original concept behind this book is to obliterate the differences in the information about the Sarwari Qadri Spiritual Guides which have arisen over the passage of time as well as to meet the need of the availability of authentic and relevant historical material about them.
