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.
