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 And if a wave enshroudeth them like awnings, they cry unto Allah, making their faith pure for Him only. But when He bringeth them safe to land, some of them compromise. None denieth Our signs save every traitor ingrate. 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 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
