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 waves engulf them (in the sea) like canopies, they call upon Allah, consecrating their faith solely to Him. But when He delivers them safely to the land, some of them become lukewarm. None denies Our Signs except the perfidious, the ungrateful. 32 O MEN! Be conscious of your Sustainer, and stand in awe of the Day on which no parent will be of any avail to his child, nor a child will in the least avail his parent! Verily, God's promise [of resurrection] is true indeed: let not, then, the life of this world delude you, and let not [your own] deceptive thoughts about God delude you! 33 Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware. 34
