A book in English in which its author wrote, "This is a call for salvation which I would like to present to every wise person, hoping that Allah, The All omnipotent and The All-Sublime, would guide by it those who have gone astray, and that He may reward me bountifully and reward everyone who participates in distributing it. 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. This book, The Religion of Truth, treats these basic and great subjects. I have indicated in the foot-notes the meaning of some words and the explanation of some subjects, basing these explanations on The Holy Quran and the traditions of Prophet Muhammad, may the peace and blessings of Allah be upon him, because these two are the only sources of Islam, the religion of truth."
