For this reason, the falsity of the implications is taken as proof of the falsity of the thing implied. If one wishes to formulate the proof in this manner, one says:
If the report possessed a meaning that is neither knowledge nor anything akin to it, then either knowledge necessarily entails its truthfulness or it does not.
If knowledge necessarily entails its truthfulness, it would no longer be possible to know that this meaning is something other than knowledge, for the only evidence for that claim would be the hypothetical conjunction of knowledge with inward falsehood. Yet, since knowledge necessarily produces inward truthfulness and excludes inward falsehood, that hypothesis is impossible. Hence, it cannot be known that the report has any meaning (1) other than knowledge, whether with respect to the Creator or to His servants. Anyone who makes such a claim would therefore be speaking about Allah’s speech and reports without any knowledge or evidence whatsoever, and that is unanimously forbidden. This, in itself, invalidates their position—that is, they have spoken without a shred of proof.
But if knowledge neither entails inward truthfulness nor negates inward falsehood, they would have no path to establish an inward speech that is itself truth (2), for knowledge would neither necessitate it nor preclude its opposite. One could not appeal to knowledge to prove it, and anything else they mention besides knowledge can only show that Allah is truthful in general and that falsehood is impossible for Him—an issue on which no one disagrees. Nevertheless, they (3) remain unable to prove an inward speech that is truth; the evidence that Allah is truthful is of the same order as the evidence that He speaks, yet this does not aid them in proving the inward speech they claim uniquely for themselves. Likewise, it does not help them establish the truthful inward meaning of the report (4) that they alone among the schools have affirmed, innovated, and by which they have cut themselves off from the Muslim community—a singularity they themselves acknowledge, as al-Maḥṣūl records (5).
