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.
These are three good books for learning Arabic Language for the non-native speakers. But we should pay your attention that they are for who has slightly good knowledge about Arabic and how to pronounce it. We don't claim that you can consider them as an alternative to a teacher but they are good step for who wants to be excellent at Arabic. With these books, there is an Arabic-English glossary confined to the words mentioned in these books, and the author shows in its introduction how to find any word.
This book is one of the most important Islamic books which gives right answers about Christianity.
