28. It should be noted that two kinds of the men are being contrasted here. First, those who turn to Allah when a calamity befalls them, but worship others than Allah normally. Second, those who have made it their permanent way of life to obey Allah and worship and serve Him, and their worshiping Him in solitude during the night is a proof of their sincerity. The first kind of the men have been called ignorant by Allah, even if they might have devoured whole libraries. And the second kind of the men have been called the learned, even if they might be illiterate. For the real supremely important thing is the knowledge of the truth and man’s action according to it, and on this depends his true success. Allah asks: How can these two be equal? How can they possibly follow the same way together in the world, and meet with the same end in the Hereafter?
