Art thou not aware how the ships speed through the sea by God's favour, so that He might show you some of His wonders? Herein, behold, there are messages indeed for all who are wholly patient in adversity and deeply grateful [to God]. 31 For [thus it is with most men:] when the waves engulf them like shadows [of death,] they call unto God, sincere [at that moment] in their faith in Him alone; but as soon as He has brought them safe ashore, some of them stop half-way [between belief and unbelief]. Yet none could knowingly reject Our messages unless he be utterly perfidious, ingrate. 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 Lo! Allah! With Him is knowledge of the Hour. He sendeth down the rain, and knoweth that which is in the wombs. No soul knoweth what it will earn to-morrow, and no soul knoweth in what land it will die. Lo! Allah is Knower, Aware. 34
