Do you not see that the ships run on in the sea by Allah's favor that He may show you of His signs? Most surely there are signs in this for every patient endurer, grateful one. 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 O mankind! do your duty to your Lord, and fear (the coming of) a Day when no father can avail aught for his son, nor a son avail aught for his father. Verily, the promise of Allah is true: let not then this present life deceive you, nor let the chief Deceiver deceive you about Allah. 33 Verily Allah! with Him alone is the knowledge of the Hour, and He it is who sendeth down the rain and knoweth that which is in the wombs: and no person knoweth whatsoever it shall earn on the morrow, and a person knoweth not in whatsoever land he shall die. Verily Allah is Knowing, Aware. 34
