“It is believed,” writes Lieut.-Col. P. M. Sykes, “that the twelfth Imám never died, but in A.H. 260 (873) disappeared into miraculous concealment, from which he will reappear on the Day of Judgment in the mosque of Gawhar-Shád at Mashhad, to be hailed as the Mihdí or ‘Guide’ and to fill the earth with justice.”
