This book is published on the shoulders of those people who have volunteered their personal stories of how they entered Islam. If you, the reader, are open to the possibility that Allah, the Creator, has given you clear evidence to accept Him and His message of Islam, then read these stories. From different backgrounds, and different experiences, you just might find someone here who had the same questions and doubts that you may have. Many of these people have endured against tremendous obstacles, including parental opposition, despair with other religions, being blind, and being lied to about the true nature of Islam.
