Have you not seen how the ships sail on the sea by God's grace so that He may show you some of His signs? Surely therein are signs for every steadfast, thankful person. 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 people! guard against (the punishment of) your Lord and dread the day when a father shall not make any satisfaction for his son, nor shall the child be the maker of any satisfaction for his father; surely the promise of Allah is true, therefore let not this world's life deceive you, nor let the archdeceiver deceive you in respect of Allah. 33 Indeed Allah has the knowledge of the Last Day! And He sends down the rain; and He knows all what is in the mothers’ wombs; and no soul knows what it will earn tomorrow; and no soul knows the place where it will die; indeed Allah is the All Knowing, the Informer. (He may reveal the knowledge to whomever He wills.) 34
