Have you not seen how the ships sail on the sea by God's grace so that He may show you some of His signs? Surely therein are signs for every steadfast, thankful person. 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 MEN! Be conscious of your Sustainer, and stand in awe of the Day on which no parent will be of any avail to his child, nor a child will in the least avail his parent! Verily, God's promise [of resurrection] is true indeed: let not, then, the life of this world delude you, and let not [your own] deceptive thoughts about God delude you! 33 Verily Allah! with Him alone is the knowledge of the Hour, and He it is who sendeth down the rain and knoweth that which is in the wombs: and no person knoweth whatsoever it shall earn on the morrow, and a person knoweth not in whatsoever land he shall die. Verily Allah is Knowing, Aware. 34
