See you not that the ships sail through the sea by Allah's Grace? that He may show you of His Signs? Verily, in this are signs for every patient, grateful (person). 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 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
