Is the intellect the foundation of revelation?

The scholars of Kalam (theology) held that the intellect is the basis of revelation, in the sense that revealed scripture is affirmed through rational means. This is because it is the intellect that indicates the possibility of divine revelation and establishes its wisdom and its actual occurrence. It further provides evidence to validate the prophethood of Muhammad (peace and blessings be upon him) and verify his message. Had we doubted its veracity through reason, the traditional arguments would have broken down. Yet after having propounded these decisive proofs for the prophethood of Muhammad (peace and blessings be upon him), that he is the messenger of God and that the scripture he came with is truly of divine provenance, little is left to the intellect except receive the message, preserve it, and convey it to others. It does not become a believing man or woman, when God and his messenger have decided a matter, that they should [then] claim any say in their affair [33:36].
