Do you not see that ships sail through the sea by the favor of Allah that He may show you of His signs? Indeed in that are signs for everyone patient and grateful. 31 When a wave covers them like the canopy (of clouds), they call to Allah, offering Him sincere devotion. But when He has delivered them safely to land, there are among them those that halt between (right and wrong). But none reject Our Signs except only a perfidious ungrateful (wretch)! 32 O men, seek protection with your Lord and fear the Day when neither will the father be of any avail to his son, nor will the son be of any avail to his father. God's promise is surely true. So let not worldly life beguile you, nor let the Deceiver deceive you concerning God. 33 Only God has the knowledge of the Hour. He sends rain from the heavens, and knows what is in the mothers' wombs. No one knows what he will do on the morrow; no one knows in what land he will die. Surely God knows and is cognisant. 34
