Introduction
My Father, Mr. Abul Hashim, died on October 5, 1974 shortly before this book was published. It could have been published during his lifetime if the cover designer did not take a long time to finish his work. A mistake was also made in writing the name of the book. In this second edition the mistake has been corrected.
The preface written by the author for the book could not be found at the time of printing and I am sure that it was not brought to the notice of the author, and so it was published without that. Later the preface was found after his death and it is now being printed in this edition.
A second of this book should have been published long ago but owing to various reasons it could not be done. I thank the Co-operative Book Society and also Mr. Munawwar Ahmed for bringing out this edition.
