Do you not see that ships sail through the sea by the favor of Allah that He may show you of His signs? Indeed in that are signs for everyone patient and grateful. 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 people, fear your Lord and dread the day when no father will avail a son, nor son his father. Truly the promise of God is true. Do not be deluded by the life of this world, and do not let the deceiver draw you away from 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
