This book was first published in 1971 as a part of the Islamic Correspondence Course, run by the Bilal Muslim Mission of Tanzania. Since then it has been reprinted several times in Tanzania and Kenya.

Now I have thoroughly revised and enlarged it; and my son, Maulana Sayyid Muhammad Rizvi (Toronto), has rendered a great service by editing and annotating the book and streamlining its arrangement.

I hope this edition will prove even more popular than the previous one.
