Do you not see that the ships sail in the ocean by the grace of God, that He may show you some of His glories. Verily there are signs in this for those who are constant and give thanks. 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 Mankind, have fear of your Lord and the day when a father will be of no avail to his son, nor will a son carry any part of the burden of his father. The promise of God is true. Do not let the worldly life deceive you nor let your pride deceive you about God. 33 Allah, He alone has knowledge of the Hour. He sends down the rain and He knows what is in the wombs. No soul knows what he will earn tomorrow; and no soul knows in what land it will die. Surely, Allah is the Knower, the Aware. 34
