Divine grace (salvation) is felt to be especially potent in places visited by Jesus Christ or Saints or by Mary; where they have appeared in visions. Major pilgrimage centers include Lourdes where visions of the Virgin Mary were first seen in 1858 and where healing has been occuring since that time. (John R. Hinnells, ed., Dictionary of Religions, Middlesex, England: Penguin Books Ltd., 1984, p. 284)]. It also occurs to heretical Muslims who call on the dead or those not present, and the devils take the form of the one called upon even without him realizing it. I know of many cases where this has occurred and the people called upon have told me that they did not know that they were called upon, though those beseeching them for help saw their images and were convinced that it was the actual person. More than one person has mentioned that they called on me in times of distress, each telling a different story about how I have responded. When I told them that I never answered any of them nor did I know that they were calling on me, some said that it must have been an angel. I told them that angels do not benefit those committing SHIRK and that it was actually a devil trying to further misguide them.
