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 when the waves cover them like shadows they call upon God, making their religion sincerely His; but when He has delivered them to the land, some of them are lukewarm. And none denies Our signs, except every ungrateful traitor. 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 Surely God -- He has knowledge of the Hour; He sends down the rain; He knows what is in the wombs. No soul knows what it shall earn tomorrow, and no soul knows in what land it shall die. Surely God is All-knowing, All-aware. 34
