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 And when a wave covers them like shades (i.e. like clouds or the mountains of sea-water), they invoke Allah, making their invocations for Him only. But when He brings them safe to land, there are among them those that stop in the middle, between (Belief and disbelief). But none denies Our Signs except every perfidious ungrateful. 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
