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 waves engulf them (in the sea) like canopies, they call upon Allah, consecrating their faith solely to Him. But when He delivers them safely to the land, some of them become lukewarm. None denies Our Signs except the perfidious, the ungrateful. 32 People, fear your Lord, and fear the Day when no father shall ransom a thing for his child nor a child for his father. The promise of Allah is surely true. So do not let the life of this present world delude you, nor let the deluder (satan) delude you concerning Allah. 33 Verily Allah! with Him alone is the knowledge of the Hour, and He it is who sendeth down the rain and knoweth that which is in the wombs: and no person knoweth whatsoever it shall earn on the morrow, and a person knoweth not in whatsoever land he shall die. Verily Allah is Knowing, Aware. 34
