Pattern in Surah Al-Kahf (The Cave) [Quran Chapter 18]

Surah Al-Kahf has a total of 110 verses. Verse 1 contains the statement: Praise be to Allah, Who hath sent to His Servant the Book, and hath allowed therein no Crookedness [Translator: Yusuf Ali]. Following this powerful statement of accuracy are some amazing, mind-boggling stories, containing lessons for trials in faith, wealth, knowledge and power!  

This Surah is titled Al-Kahf meaning The Cave, and the first of the four stories related in this surah is about the people of the cave, who took refuge in the cave when they fled religious persecution (verses 9-26). The second story is about the two flourishing gardens whose owner was an ingrate. The question posed is that what if the water sinks in the ground and cannot be found (verses 32-43). In the third story about Moses’ travel (verses 60-82), the fish strangely disappears near a rock, and the poor fisherman’s boat is saved from being confiscated by making a hole in the boat. In the last story (verses 83-98), Dhu-ul-Qarnayn, visits three places: the first visit is to the Arctic Ocean in autumn (verse 86), and second to Antarctica, where there is a hole in the ozone in spring (verse 90), and the last in which he seals an opening in between the mountains to keep the mischief-makers from coming out.  

It is interesting that this Surah contains four unique stories, each with subterranean references. In the first story, the people are rescued from religious persecution by being made to sleep in a cave; in the second story about the two flourishing gardens, with water flowing between the two, the question posed is what if the water disappears underground; in the third, the fish escapes miraculously by a rock; and in the last, the opening between the mountain-sides is sealed to contain the mischief-mongers within. 

Observing the pattern of verses ending with one, the following pattern emerges:

71	made a hole in the boat	God saves from loss through an apparent loss
81	Lord may give better in exchange	God might replace with something better
91	We completely knew / had full knowledge	God encompasses everything in His Knowledge

The surah ends with the following statement [Verse 110]: Say: I am only a mortal like you. My Lord inspireth in me that your Allah is only One Allah. And whoever hopeth for the meeting with his Lord, let him do righteous work, and make none sharer of the worship due unto his Lord. [Translator: Pickthall]
