Seest thou not that the ships sail through the ocean by the Grace of Allah?- that He may show you of His Signs? Verily in this are Signs for all who constantly persevere and give thanks. 31 When the waves overshadow them like a canopy, they pray to God with all-exclusive faith in Him. But after He has safely brought them to the shore, there are some who vacillate between doubt and belief, but no one rejects Our signs except those who are perverse and disbelieve. 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 Indeed, Allah [alone] has knowledge of the Hour and sends down the rain and knows what is in the wombs. And no soul perceives what it will earn tomorrow, and no soul perceives in what land it will die. Indeed, Allah is Knowing and Acquainted. 34
