“Malcolm X, an American civil rights activist, describes the sociological atmosphere he experienced at his Hajj in the 1960s as follows:
There were tens of thousands of pilgrims, from all over the world. They were of all colors, from blue-eyed blondes to black-skinned Africans. But we were all participating in the same ritual, displaying a spirit of unity and brotherhood that my experiences in America had led me to believe never could exist between the white and the non-white. America needs to understand Islam, because this is the one religion that erases from its society the race problem. You may be shocked by these words coming from me. But on this pilgrimage, what I have seen, and experienced, has forced me to rearrange much of my thought patterns previously held.[59]”
