Hast thou not seen how the ships glide on the sea by Allah's grace, that He may show you of His wonders? Lo! therein indeed are portents for every steadfast, grateful (heart). 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 Mankind, have fear of your Lord and the day when a father will be of no avail to his son, nor will a son carry any part of the burden of his father. The promise of God is true. Do not let the worldly life deceive you nor let your pride deceive you about God. 33 Allah, He alone has knowledge of the Hour. He sends down the rain and He knows what is in the wombs. No soul knows what he will earn tomorrow; and no soul knows in what land it will die. Surely, Allah is the Knower, the Aware. 34
