In order to become a Muslim, there are no specific religious rituals or customs that you need to perform, neither in specific areas nor in front of people.
The book is dedicated to non-Muslims who desire to know Islam in brief and look forward to know its most important teachings. We hope the book will also be useful for Muslims as well as the newly converted. The book has been translated to many languages, and its core shall be a basis to a new huge site that is being prepared now.
