Have you not seen that the ships sail in the ocean through the bounty of God so that He may show you the evidence (of His existence). There is evidence (of the truth) in this for every forbearing and grateful one. 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, Allah! With Him (Alone) is the knowledge of the Hour, He sends down the rain, and knows that which is in the wombs. No person knows what he will earn tomorrow, and no person knows in what land he will die. Verily, Allah is All-Knower, All-Aware (of things). 34
