Have you not seen that the ships sail in the ocean through the bounty of God so that He may show you the evidence (of His existence). There is evidence (of the truth) in this for every forbearing and 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 men, seek protection with your Lord and fear the Day when neither will the father be of any avail to his son, nor will the son be of any avail to his father. God's promise is surely true. So let not worldly life beguile you, nor let the Deceiver deceive you concerning God. 33 Verily, with God alone rests the knowledge of when the Last Hour will come; and He [it is who] sends down rain; and He [alone] knows what is in the wombs; whereas no one knows what he will reap tomorrow, and no one knows in what land he will die. Verily; God [alone] is all-knowing, all-aware. 34
