In ancient times the people of America were, through their northern regions, close to Asia, that is, separated from Asia by a strait. For this reason, it hath been said that crossing had occurred. There are other signs which indicate communication.
As to places whose people were not informed of the appearance of Prophets, such people are excused. In the Qur’án it hath been revealed: “We will not chastise them if they had not been sent a Messenger.”1
Undoubtedly in those regions the Call of God must have been raised in ancient times, but it hath been forgotten now.
