And their Prophet said unto them: Lo! the token of his kingdom is that there shall come unto you the ark wherein is peace of reassurance from your Lord, and a remnant of that which the house of Moses and the house of Aaron left behind, the angels bearing it. Lo! herein shall be a token for you if (in truth) ye are believers.
