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 And when the waves cover them like shadows they call upon God, making their religion sincerely His; but when He has delivered them to the land, some of them are lukewarm. And none denies Our signs, except every ungrateful traitor. 32 O men, fear your Lord, and dread a day when no father shall give satisfaction for his child, and no child shall give satisfaction for his father whatever. Surely God's promise is true; so let not the present life delude you, and let not the Deluder delude you concerning God. 33 Verily, with God alone rests the knowledge of when the Last Hour will come; and He [it is who] sends down rain; and He [alone] knows what is in the wombs; whereas no one knows what he will reap tomorrow, and no one knows in what land he will die. Verily; God [alone] is all-knowing, all-aware. 34
