The ruling on using fitrah (the innate natural disposition) and reason as evidence for Allah without the Messengers

Question:
Peace be upon you. You recently told the story of a child who grew up on an island where there was no one, and he used his reason to discover that he has a Lord, that his Lord is the One who created him, and that he is weak. So we held the view that Allah guided some of you to Him through reason, and that the Messengers merely followed that and made it appealing. Is this considered following reason?

Answer:
There is no doubt that the sound fitrah (innate natural disposition) is a favor from the Lord, Glorified and Exalted is He. However, if the fitrah changes, it becomes corrupted by upbringing, company, and association. But the fitrah does not stand alone; it is necessary to send the Messengers and send down the Books in order to complete the fitrah, to complete it and direct it. There is no doubt that Allah, Mighty and Majestic, is known through the fitrah, through reason, and through revelation. There is much evidence for the Lord of the Worlds, Glorified and Exalted is He. But the fitrah does not stand alone, and reason does not stand alone, and they are not sufficient. It is necessary to send down the Books and send the Messengers. For this reason, He, Mighty and Majestic, said: They guide. He did not limit creation to their fitrah and their reason, because He knows, Glorified is He, that these fitrahs and these minds, even though they know the Lord, Glorified is He, do not stand alone in that and do not grasp all matters. And even if they grasp them in general, they do not grasp them in detail. So this writing has some validity, but the exaggeration in deifying reason is what is forbidden.
