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 covereth them like awnings, they call upon Allah, making their religion pure for Him. Then when He delivereth them on the land, only some of them keep to the middle course. And none gainsaith Our signs save each perfidious, ingrate one. 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 Only God has the knowledge of the coming of the Hour of Doom. He sends down the rain and knows what is in the wombs. No soul is aware of what it will achieve tomorrow and no soul knows in which land it will die. God is All-knowing and All-aware. 34
