A book contains sunnahs (recommended acts) scattered in a lot of books. It’s divided into two main sections. The first is concerned with good deeds that have specified rewards whose benefits are restricted to whoever performs them only. Examples of such good deeds are: praying sunnahs and performing ‘umrah. The second section is devoted to the deeds with unspecified benefits, i.e. the good deeds whose benefits reach others like the family, the neighbor or even the community in large. These benefits are achieved in this life as well as the Last Day. Giving charity and useful knowledge are examples of this group of good deeds.

This book, The Religion of Truth, treats these basic and great subjects. We should know that the only way for our salvation in this life and in the hereafter is to know, for sure, our Lord who created us, believe in Him, and worship Him Alone. We should also know our prophet whom Allah had sent to us and to mankind, believe in Him and follow him. We should know the Religion of Truth which our Lord has commanded us to believe in and practice it.
