3860 Allah's Truth is so vast that no man in this life can compass the whole of it. But Allah in His mercy selects His servants on whom it is cast like a mantle. They see enough to be able to teach their fellow men. It is through that mantle -that mission received from Allah-that a messenger can speak with authority to men. He cannot explain the exact mystery of inspiration, but he knows it is from Allah, and this is his third argument.
