Art thou not aware how the ships speed through the sea by God's favour, so that He might show you some of His wonders? Herein, behold, there are messages indeed for all who are wholly patient in adversity and deeply grateful [to God]. 31 And if a wave comes upon them like mountains, they pray to Allah believing purely in Him; then when He brings them safely to land, some of them remain upon justice; and none will deny Our signs except an extremely unfaithful, ungrateful person. 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, 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
