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 When the waves engulf them like shadows [of death], they call to God, sincere [at that moment] in their faith in Him alone: but as soon as He has brought them safe ashore, only some of them take the right course. And none denies Our signs save the perfidious and 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 Verily the knowledge of the Hour is with Allah (alone). It is He Who sends down rain, and He Who knows what is in the wombs. Nor does any one know what it is that he will earn on the morrow: Nor does any one know in what land he is to die. Verily with Allah is full knowledge and He is acquainted (with all things). 34
