“on thy brow
Shall sit a nobler grace than now.

The thronging years in glory rise.
And, as they fleet,
Drop strength and riches at thy feet.”

There would be no persecuted Galileo in Islam, because Islam, unlike Christianity, did not force people to believe in a “fixed” heaven.”
—Fatima Mernissi, Moroccan sociologist. Islam and Democracy, ch. 9, Addison-Wesley Publishing Co. (Trans. 1992)
