The Victory of the Byzantine

It is impossible for a person who cannot read and write to inform about the Ghayb (unseen, unknown) and the information given by him to turn out to be right all the time. When we divide the Ghayb into two as future and past, it is not possible for someone to inform about the future at all. In order to give information about the past, that person must be literate and have to study works about the past if the given news is not well known and not something that people talk about in their daily lives.
