Malcolm X disowned Islam

Malcolm X, in a letter from Mecca to a friend, NYT, 4 Oct 1964, p.59:

For 12 long years I lived within the narrow minded confines of the "straightjacket world" created by my strong belief that Elijah Muhammad was a messenger direct from God Himself, and my faith in what I now see to be a pseudo-religious philosophy that he preaches. . . . I shall never rest until I have undone the harm I did to so many well-meaning, innocent Negroes who through my own evangelistic zeal now believe in him even more fanatically and more blindly than I did.
