“One of our fan-coloring biographers, who paints small men as very great, inquired of me lately with real affection too, whether he might consider as authentic, the change of my religion much spoken of in some circles. Now this supposed that they knew what had been my religion before, taking for it the word of their priests, whom I certainly never made the confidants of my creed. My answer was "say nothing of my religion. It is known to my God and myself alone. Its evidence before the world is to be sought in my life; if that has been honest and dutiful to society, the religion which has regulated it cannot be a bad one."”

The Ballot or the Bullet (1964), Speech in Detroit, Michigan (12 April 1964)
Context: Islam is my religion, but I believe my religion is my personal business. It governs my personal life, my personal morals. And my religious philosophy is personal between me and the God in whom I believe; just as the religious philosophy of these others is between them and the God in whom they believe. And this is best this way. Were we to come out here discussing religion, we’d have too many differences from the outstart and we could never get together. [... ] If we bring up religion, we’ll be in an argument, and the best way to keep away from arguments and differences, as I said earlier, put your religion at home in the closet. Keep it between you and your God. Because if it hasn’t done anything more for you than it has, you need to forget it anyway.

Context: Once more I felt myself rising through space. It was even as the Sphere had said. The further we receded from the object we beheld, the larger became the field of vision. My native city, with the interior of every house and every creature therein, lay open to my view in miniature. We mounted higher, and lo, the secrets of the earth, the depths of mines and inmost caverns of the hills, were bared before me.Awestruck at the sight of the mysteries of the earth, thus unveiled before my unworthy eye, I said to my Companion, "Behold, I am become as a God. For the wise men in our country say that to see all things, or as they express it, OMNIVIDENCE, is the attribute of God alone." There was something of scorn in the voice of my Teacher as he made answer: "Is it so indeed? Then the very pick-pockets and cut-throats of my country are to be worshiped by your wise men as being Gods: for there is not one of them that does not see as much as you see now. But trust me, your wise men are wrong."

Context: Why should they ask me to put on a uniform and go 10,000 miles from home and drop bombs and bullets on Brown people in Vietnam while so-called Negro people in Louisville are treated like dogs and denied simple human rights? No I’m not going 10,000 miles from home to help murder and burn another poor nation simply to continue the domination of white slave masters of the darker people the world over. This is the day when such evils must come to an end. I have been warned that to take such a stand would cost me millions of dollars. But I have said it once and I will say it again. The real enemy of my people is here. I will not disgrace my religion, my people or myself by becoming a tool to enslave those who are fighting for their own justice, freedom and equality. If I thought the war was going to bring freedom and equality to 22 million of my people they wouldn’t have to draft me, I’d join tomorrow. I have nothing to lose by standing up for my beliefs. So I’ll go to jail, so what? We’ve been in jail for 400 years.
