This book is a translation of the Arabic book Sameer-ul-Mo'minat wa anees-us-Salehat.
A persual of the book will bring many things to light. The first thing is the introduction of famous Muslim ladies, besides this their short biographies, their special achievements, their services in the cause of Islam and so on.
the author also mentions a few non-Muslim women. There are two reasons for this. First, they have been mentioned because of their relevance to the title of the chapter, secondly to show what kept them away from Islam.
