Do you not see that the ships run on in the sea by Allah's favor that He may show you of His signs? Most surely there are signs in this for every patient endurer, grateful one. 31 And if a wave enshroudeth them like awnings, they cry unto Allah, making their faith pure for Him only. But when He bringeth them safe to land, some of them compromise. None denieth Our signs save every traitor ingrate. 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 Surely Allah alone has the knowledge of the Hour. It is He Who sends down the rain and knows what is in the wombs, although no person knows what he will earn tomorrow, nor does he know in which land he will die. Indeed, Allah is All-Knowing, All-Aware. 34
