The Persians hold that at the last judgment every man must pass along a bridge no wider than a razor's edge; that the unbelievers and the wicked will certainly in their passage fall into hell, there to be for ever and ever tormented; but that the faithful shall be so guided and supported that they shall pass the bridge swifter than a bird can fly through the air, and enter into paradise, and seat themselves on the banks of the river of delight, which, they say, is shaded by a tree of such immense size, that if a man were to ride forty thousand years, he would not pass the extent of one of its leaves. In Persia it was a common belief that there were many prophets living between the days of Adam and Mohammed, who were created before the world was made. Their prophets, according to history, were possessed of the power of working miracles; and charms and amulets were common in the country. Pilgrims who went to Mecca invariably kissed a black stone, regarding which there is a curious legend: Abraham, we are informed, tied his camel to this stone when he went to sacrifice Ishmael, for the Mohammedans represent Hagar as Abraham's lawful wife, and Ishmael his heir. There is another tradition, that when Abraham was about to build the Kaaba, held in great veneration, the stones marched thither of themselves ready hewn and polished, and that the black stone, being left out when the building was completed, demanded of Abraham why it had not been used in the sacred structure. The prophet told the stone not to be disappointed, for he would cause it to be more honoured than any stone in the building, by commanding all the faithful to kiss it as they went in procession. The faithful people were wont to meet at the place which they supposed was Adam and Eve's trysting place after the expulsion, for it is related in one of their legends that the first man and woman wandered about the world, separately, hundreds of years after the Fall.
