An Explanation of the Virtue of Islam is a classic treatise by Shaykh Muhammad ibn ‘Abdul Wahhāb (may Allah have mercy on him) that clarifies the essential qualities, foundations, and etiquette of the religion of Islam. In about 184 pages, this work outlines the virtues that a believer must uphold, the prohibitions that must be avoided, and the balance between dawah (calling others) and purification of the self.
The book teaches that Islam is not merely a set of rituals, but a comprehensive system encompassing belief, manners, ethics, and sincerity. It underscores the inseparable link between Islam and the Sunnah: “Know that Islam is the Sunnah, and the Sunnah is Islam — one cannot be established without the other.” It gives special attention to how a da‘i (caller) or learner should present these virtues: with clarity, mercy, wisdom, and adherence to the way of the Salaf.
Throughout the book, the author presents scriptural evidence, meaningful aphorisms, and concise chapters designed for reflection, memorization, and character reform. The underlying aim is to revive the believer’s understanding of what Islam truly demands — sincerity in worship, avoidance of innovation, dedication to mercy, and a life of upright conduct. It is suitable for students, callers, seekers of purification, and all who wish to deepen their commitment to Islam.
Imaam al-Barbahaari (rahimahullaah) said: All praise is for Allaah who guided us to Islaam and blessed us with it and placed us in the best nation, so we ask Him to grant us that we keep to that which He loves and is pleased with and avoid that which He hates and which angers Him. Know that Islam is the Sunnah, and the Sunnah is Islam [1], and one of them cannot be established without the other.
"It is befitting for the caller and the student of knowledge who calls to Allah to give concern to these virtues: it is his product which he spreads in his call."
