From the book:

This is a treatise by Shaykh al-Islām Muḥammad ibn ʿAbd al-Wahhāb (May Allah have mercy upon him), as attributed to him by Shaykh ʿAbd al-Raḥmān ibn Qāsim (May Allah have mercy upon him) in al-Durar al-Saniyyah and by Shaykh Muḥammad ibn Māniʿ (May Allah have mercy upon him) in his commentary on the treatise. The style is not far from that of Shaykh al-Islām (May Allah have mercy upon him) and includes discussions on the types of True Islāmic Monotheism, polytheism, and hypocrisy. All of these are derived from the Qurʾān and the Sunnah through analysis and scrutiny, for the purpose of clarification, comprehension, and explanation of the rulings regarding each.
