Hast thou not seen how the ships glide on the sea by Allah's grace, that He may show you of His wonders? Lo! therein indeed are portents for every steadfast, grateful (heart). 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 God -- He has knowledge of the Hour; He sends down the rain; He knows what is in the wombs. No soul knows what it shall earn tomorrow, and no soul knows in what land it shall die. Surely God is All-knowing, All-aware. 34
