Do you not see that ships sail through the sea by the favor of Allah that He may show you of His signs? Indeed in that are signs for everyone patient and grateful. 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! Keep your duty to your Lord and fear a Day when the parent will not be able to avail the child in aught, nor the child to avail the parent. Lo! Allah's promise is the very truth. Let not the life of the world beguile you, nor let the deceiver beguile you, in regard to Allah. 33 Surely God -- He has knowledge of the Hour; He sends down the rain; He knows what is in the wombs. No soul knows what it shall earn tomorrow, and no soul knows in what land it shall die. Surely God is All-knowing, All-aware. 34
