Observest thou not that the ship saileth in the sea by the favour of Allah that he may shew you of His signs? Verily therein are signs for every persevering, grateful heart. 31 When the waves engulf them like shadows [of death], they call to God, sincere [at that moment] in their faith in Him alone: but as soon as He has brought them safe ashore, only some of them take the right course. And none denies Our signs save the perfidious and ungrateful person. 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 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
