Some Quranic verses indicate knowledge of the unseen to belong only to God; while according to some others, such ability has been also given to some special people. Commentators for solving the problem have noticed the matter that what is meant by knowledge during the age of messengership and after that includes essential knowledge not accidental and the claim for such knowledge means Divinity. In this way undoubtedly many differences between God and servants remain in its place. It is not, therefore, reasonable to view messengers as being of knowledge of the unseen; because such a belief would be equal to polytheism. In this way, it becomes clear that God`s knowledge differs with that of servants. The former is essentially and the latter accidentally bestowed upon servants.
