is One who speaks, and knowledge that He is a Speaker comes only after knowing [that] (1) He is living. Knowledge that He is living, in turn, follows the recognition that He is an Agent, which itself follows (2) knowledge of the act and that the universe is His act. This necessarily entails knowing that He is powerful [and that He possesses power] (3), that He is knowing and possesses knowledge, that He is willing and possesses (4) will, together with every other attribute without whose acknowledgment knowledge of God Most High is not sound—these being among the prerequisites of faith (5).
He said (6): “Revelation has further added other conditions, namely, that nothing indicating unbelief—whether by commission or omission—be joined to that faith. Thus, the Sacred Law has commanded him (7) to refrain from bowing and worshipping an idol; were he to do so, it would signal his unbelief. Likewise, if he were to kill a prophet or treat him with contempt, that would signify unbelief; if he failed to venerate the muṣḥaf (written copy of the Quran) or the Kaʿbah, that too would signify unbelief. In the same way, if he opposed the unanimous consensus of both specialists and laypeople on any matter upon which they all agree, such opposition would point to unbelief. Therefore, should any one of these acts—each of which the Law rules cannot coexist with faith—be found alongside what must accompany faith, that fact would show us that the affirmation (taṣdīq) which is īmān is absent from his heart (8).
