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 covers them like shades (i.e. like clouds or the mountains of sea-water), they invoke Allah, making their invocations for Him only. But when He brings them safe to land, there are among them those that stop in the middle, between (Belief and disbelief). But none denies Our Signs except every perfidious ungrateful. 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 Indeed Allah has the knowledge of the Last Day! And He sends down the rain; and He knows all what is in the mothers’ wombs; and no soul knows what it will earn tomorrow; and no soul knows the place where it will die; indeed Allah is the All Knowing, the Informer. (He may reveal the knowledge to whomever He wills.) 34
