Mard e Kamil Ka Wasiat Nama was a book written by Yusuf Ali Kazab. Yusuf got this book published in 1993, however the book was so blasphemous that instead of using his own name as the author of the book, Yusuf published it with the author name being “Mard e Kamil”. Yusuf Kazab used to circulate this book within his close circles, and all his mureeds knew very well, who was the Mard e Kamil and Khalifa e Azam.
This is the same book that Zaid Hamid took with him to Moulana Niazi and read a few sentences from here and there. Zaid Hamid specially read the Intesab, page 3 of the book to Moulana Niazi and got the statement from Moulana Niazi that he is now shouting about.
Hesham A Syed has written a two page commentary on the book, which is embedded below.
