The author introduces his book by saying, As for the introduction, we have explained in it the sum- mons to God, His religion, and His path. As for the eight sections, each concerns a certain category of people, the first category being the scholars; the second the ascetics and devotees; the third the kings, the rulers, and other people in authority; the fourth the merchants, the craftsmen, and other such people; the fifth the poor, the weak, and the destitute; the sixth the dependents such as the women, children, and slaves; the seventh the generality of believers, both the obedient among them and the transgressors; the eighth those who have not responded to the summons of God and His Messenger and do not believe in God and the Last Day. Finally, in conclusion, we give brief counsels of advice to all eight categories, in addition to general counsels and exhortations that soften the heart, the completion of which closes the book.
