Do you not see that the ships run on in the sea by Allah's favor that He may show you of His signs? Most surely there are signs in this for every patient endurer, grateful one. 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 mankind! do your duty to your Lord, and fear (the coming of) a Day when no father can avail aught for his son, nor a son avail aught for his father. Verily, the promise of Allah is true: let not then this present life deceive you, nor let the chief Deceiver deceive you about Allah. 33 Truly, God alone has knowledge of the Hour. He sends down the rain, and He knows what is in the wombs. No soul knows what it will earn tomorrow, and no soul knows in what land it will die. Surely, God is all knowing, all-aware. 34
