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 the waves overshadow them like a canopy, they pray to God with all-exclusive faith in Him. But after He has safely brought them to the shore, there are some who vacillate between doubt and belief, but no one rejects Our signs except those who are perverse and disbelieve. 32 O men, fear your Lord, and dread a day when no father shall give satisfaction for his child, and no child shall give satisfaction for his father whatever. Surely God's promise is true; so let not the present life delude you, and let not the Deluder delude you concerning God. 33 Verily, with God alone rests the knowledge of when the Last Hour will come; and He [it is who] sends down rain; and He [alone] knows what is in the wombs; whereas no one knows what he will reap tomorrow, and no one knows in what land he will die. Verily; God [alone] is all-knowing, all-aware. 34
