Did you not see that the ship sails on the sea by Allah’s grace, so that He may show you some of His signs? Indeed in this are signs for every greatly enduring, grateful person. 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! Be afraid of your Lord (by keeping your duty to Him and avoiding all evil), and fear 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 (worldly) present life deceive you, nor let the chief deceiver (Satan) deceive you about Allah. 33 Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware. 34
