See what curiosity-arousing, attractive, necessary, and awesome truths he shows and what matters he proves. You know that what incites people most is curiosity. Suppose someone told you: “If you give half of your life and property, someone will come from Mars or Jupiter to tell you about them, your future, and what will happen to you.” If you have any curiosity at all, you would give them. But this person talks of a Monarch in Whose realm the moon flies round a moth like a fly, the moth (the earth) flutters round a lamp, and the lamp (the sun) is merely one of thousands of lamps in one of thousands of guest-houses belonging to that Monarch. He also speaks truly of so wonderful a world and predicts such a revolution that if the earth was a bomb and exploded, it would not be all that strange.
Listen to the suras he recites, which begin with: When the sun is folded up (81:1), When the heaven is cleft open (82:1), and The sudden, mighty strike (101:1). Furthermore, he speaks truly of such a future that the future in this world is, in relation to it, like a trifling mirage. He informs us most solemnly of such happiness that all worldly happiness is like a flash of lightning in comparison to an eternal sun.
