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 For [thus it is with most men:] when the waves engulf them like shadows [of death,] they call unto God, sincere [at that moment] in their faith in Him alone; but as soon as He has brought them safe ashore, some of them stop half-way [between belief and unbelief]. Yet none could knowingly reject Our messages unless he be utterly perfidious, ingrate. 32 O mankind! Fear your Lord, and fear the Day in which no father will benefit his child; nor will any good child be of any benefit to the father; indeed Allah’s promise is true; so never may the worldly life deceive you; and never may the great cheat deceive you in respect of Allah’s commands. 33 Only God has the knowledge of the coming of the Hour of Doom. He sends down the rain and knows what is in the wombs. No soul is aware of what it will achieve tomorrow and no soul knows in which land it will die. God is All-knowing and All-aware. 34
