Islam--freedom to choose belief

"God alone is the One who can monitor the real feelings of the human heart in this life, and the only one who- on the Judgment Day- will tell us of our religious disputes. It’s up to every human to choose monotheism, paganism or atheism; it’s his freedom of belief and he will be responsible before God alone on the last Day. " _ Ahmed Mansour
