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 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 O people! guard against (the punishment of) your Lord and dread the day when a father shall not make any satisfaction for his son, nor shall the child be the maker of any satisfaction for his father; surely the promise of Allah is true, therefore let not this world's life deceive you, nor let the archdeceiver deceive you in respect of Allah. 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
