Do you not see that ships sail through the sea by the favor of Allah that He may show you of His signs? Indeed in that are signs for everyone patient and grateful. 31 And when a wave like mountains covers them they call upon Allah, being sincere to Him in obedience, but when He brings them safe to the land, some of them follow the middle course; and none denies Our signs but every perfidious, ungrateful one. 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 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
