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 when a wave like mountains covers them they call upon Allah, being sincere to Him in obedience, but when He brings them safe to the land, some of them follow the middle course; and none denies Our signs but every perfidious, ungrateful one. 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 the knowledge of the Hour is with Allah (alone). It is He Who sends down rain, and He Who knows what is in the wombs. Nor does any one know what it is that he will earn on the morrow: Nor does any one know in what land he is to die. Verily with Allah is full knowledge and He is acquainted (with all things). 34
