Do you not see how the ships run upon the sea, by the Favor of Allah so that He may show you His signs? Surely, there are signs in this for every steadfast, thankful person. 31 When waves engulf them (in the sea) like canopies, they call upon Allah, consecrating their faith solely to Him. But when He delivers them safely to the land, some of them become lukewarm. None denies Our Signs except the perfidious, the 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 Verily, with God alone rests the knowledge of when the Last Hour will come; and He [it is who] sends down rain; and He [alone] knows what is in the wombs; whereas no one knows what he will reap tomorrow, and no one knows in what land he will die. Verily; God [alone] is all-knowing, all-aware. 34
