Hast thou not seen how that the ships run upon the sea by the blessing of God, that He may show you some of His signs? Surely in that are signs for every man enduring, thankful. 31 When a wave covers them like the canopy (of clouds), they call to Allah, offering Him sincere devotion. But when He has delivered them safely to land, there are among them those that halt between (right and wrong). But none reject Our Signs except only a perfidious ungrateful (wretch)! 32 O mankind, fear your Lord and fear a Day when no father will avail his son, nor will a son avail his father at all. Indeed, the promise of Allah is truth, so let not the worldly life delude you and be not deceived about Allah by the Deceiver. 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
