This volume constitutes the third section of Imam al-Ghazali’s work, *The Jewels and Pearls of the Qur’an*. It is the fortieth book in his series on the fundamentals of religion, wherein al-Ghazali categorizes the *Maqasid* (objectives) into two broad domains: knowledge and action. He further subdivides actions into the outward and the inward, and classifies the inward actions into *Tazkiyah* (purification) and *Tahliyah* (adornment). Thus, the work comprises four distinct sections: knowledge; outward actions; reprehensible character traits—from which one must purify oneself (*Tazkiyah*); and praiseworthy character traits—with which one must adorn oneself (*Tahliyah*). Al-Ghazali assigned ten fundamental principles to each of these sections, resulting in a total of forty principles.
