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 the waves, like shadows, envelop them, they call to Allah making their religion sincerely His, but no sooner does He bring them safely to land then some of them are halfhearted. None denies Our verses, except the ungrateful traitor. 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 alone has the knowledge of the Hour. It is He Who sends down the rain and knows what is in the wombs, although no person knows what he will earn tomorrow, nor does he know in which land he will die. Indeed, Allah is All-Knowing, All-Aware. 34
