“At one or another college or university, usually in the informal gatherings after I had spoken, perhaps a dozen generally white-complexioned people would come up to me, identifying themselves as Arabian, Middle Eastern or North African Muslims who happened to be visiting, studying, or living in the United States. They had said to me that, my white-indicting statements notwithstanding, they felt I was sincere in considering myself a Muslim -- and they felt if I was exposed to what they always called "true Islam," I would "understand it, and embrace it." Automatically, as a follower of Elijah, I had bridled whenever this was said. But in the privacy of my own thoughts after several of these experiences, I did question myself: if one was sincere in professing a religion, why should he balk at broadening his knowledge of that religion?
Those orthodox Muslims whom I had met, one after another, had urged me to meet and talk with a Dr. Mahmoud Youssef Shawarbi…. Then one day Dr. Shawarbi and I were introduced by a newspaperman. He was cordial. He said he had followed me in the press; I said I had been told of him, and we talked for fifteen or twenty minutes. We both had to leave to make appointments we had, when he dropped on me something whose logic never would get out of my head. He said, "No man has believed perfectly until he wishes for his brother what he wishes for himself."”
