5 : 18

مَّا لَهُم بِهِۦ مِنۡ عِلۡمٖ وَلَا لِأٓبَآئِهِمۡۚ كَبُرَتۡ كَلِمَةٗ تَخۡرُجُ مِنۡ أَفۡوَٰهِهِمۡۚ إِن يَقُولُونَ إِلَّا كَذِبٗا

5. They have no (Divine) Knowledge of it, nor had their fathers. What a grave word it is that comes out of their mouths. They say nothing but lies.

6 : 18

فَلَعَلَّكَ بَٰخِعٞ نَّفۡسَكَ عَلَىٰٓ ءَاثَٰرِهِمۡ إِن لَّمۡ يُؤۡمِنُواْ بِهَٰذَا ٱلۡحَدِيثِ أَسَفًا

6. Then perhaps you will torment yourself (O Muhammad) to death over their tracks, if they do not believe in this discourse out of sorrow.

7 : 18

إِنَّا جَعَلۡنَا مَا عَلَى ٱلۡأَرۡضِ زِينَةٗ لَّهَا لِنَبۡلُوَهُمۡ أَيُّهُمۡ أَحۡسَنُ عَمَلٗا

7. Indeed, We have made whatever is on earth as an adornment for it, so that We may test them as to which of them is best in conduct and deed ^[4].

[4]. This world is the place of striving and the Hereafter is the place of reward or punishment, where the believers will be rewarded with Paradise and the disbelievers will be punished with Hell. 
Paradise is good and none but those who are good will enter it. Allāh is Good and accepts nothing but that which is good. So the way of Allāh with the people is to test them with calamities and tribulations, so that the believer may be known from the unbeliever and so that the truthful may be distinguished from the liar.

8 : 18

وَإِنَّا لَجَٰعِلُونَ مَا عَلَيۡهَا صَعِيدٗا جُرُزًا

8. And indeed, We will certainly make all that is on it (the earth) a bare dry ground (without vegetation).

9 : 18

أَمۡ حَسِبۡتَ أَنَّ أَصۡحَٰبَ ٱلۡكَهۡفِ وَٱلرَّقِيمِ كَانُواْ مِنۡ ءَايَٰتِنَا عَجَبًا

9. Or, do you think that the companions of the cave ^[5] and the Inscription were of Our signs 'specially' wondrous ^[6]?

[5]. The seven sleepers of Ephesus.
[6]. Rather, it is only one of the many wonders of Allāh.

10 : 18

إِذۡ أَوَى ٱلۡفِتۡيَةُ إِلَى ٱلۡكَهۡفِ فَقَالُواْ رَبَّنَآ ءَاتِنَا مِن لَّدُنكَ رَحۡمَةٗ وَهَيِّئۡ لَنَا مِنۡ أَمۡرِنَا رَشَدٗا

10. When the (faithful) youths sought refuge in the cave ^[7], then they said: "Our Lord (Allāh), grant us Mercy from You, and provide for us a right course in our affair ^[8]".

[7]. Fleeing from their disbelieving people.
[8]. They asked Allāh for a means of which the end is firmness on the path to the Truth, Islam, being spared from the idolaters, gaining useful knowledge and acting upon it, so that their religious and worldly affairs would be on the right side.

11 : 18

فَضَرَبۡنَا عَلَىٰٓ ءَاذَانِهِمۡ فِي ٱلۡكَهۡفِ سِنِينَ عَدَدٗا

11. So We sealed up their ears ^[9] (and caused them to fall into a deep sleep) in the cave for a number of years.

[9]. Their ears are specifically mentioned because the sense of hearing above and beyond any other sense is the one that spoils sleep most. If done in perfect circumstances, rarely is sleep disturbed by a cause other than noise.

12 : 18

ثُمَّ بَعَثۡنَٰهُمۡ لِنَعۡلَمَ أَيُّ ٱلۡحِزۡبَيۡنِ أَحۡصَىٰ لِمَا لَبِثُوٓاْ أَمَدٗا

12. Then We raised them up ^[10] so that We might make evident which of the two parties was best able to calculate the time for which they stayed (in the Cave, sleeping) .

[10]. From that sleep. Sleep is a kind of death.

13 : 18

نَّحۡنُ نَقُصُّ عَلَيۡكَ نَبَأَهُم بِٱلۡحَقِّۚ إِنَّهُمۡ فِتۡيَةٌ ءَامَنُواْ بِرَبِّهِمۡ وَزِدۡنَٰهُمۡ هُدٗى

13. We relate to you (Muhammad) their story in truth. Indeed, they were youths who believed in their Lord (Allāh alone) and We increased them in guidance ^[11].

[11]. Youth is the most vital stage of life, worthy to make the best use of it and to strive toward excellence. Youngsters are full of energy and vivid passions. Their road is paved with hope, persistence and enlightened thinking. Indeed, it is the period of beneficial production for generations to come. Muslim youth must be aware of the essential importance and value of their life, direct it to the right way in order to achieve the best outcome.
Islamic history has a myriad of examples of great Muslim youth who were luminaries of humanity. We remind you of young believers who gathered around the Prophet (peace be upon him) to name a few, Zaid bin Thabet (may Allah be pleased with him) who collected the whole text of the Holy Qur’an, and Mus’ab bin Umair (may Allah be pleased with him) who was the first ambassador in Islam. He was asked by Prophet Muhammad (peace be upon him) to go to Madina to teach the Qur’an and through him and his teachings the people of Madina converted to Islam, Usama bin Zayd, Ibn Abbas, and Hassan and Husain (may Allah be pleased with them all).
The Messenger of Allah said: 'Hasan and Husain will be the leaders of the youth of Paradise, and their father is better than them."
And in this chapter Allāh relates the story of the 'faithful' youths who believed in their Lord 'Allāh alone'.

14 : 18

وَرَبَطۡنَا عَلَىٰ قُلُوبِهِمۡ إِذۡ قَامُواْ فَقَالُواْ رَبُّنَا رَبُّ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ لَن نَّدۡعُوَاْ مِن دُونِهِۦٓ إِلَٰهٗاۖ لَّقَدۡ قُلۡنَآ إِذٗا شَطَطًا

14. And We strengthened their hearts, when they stood up ^[12] and said: "Our Lord (Allāh) is the Lord of the heavens and the earth; never shall we invoke besides Him any god, (if we invoke others), then indeed our invoking would be too far away (from the Truth)!

[12]. Before their king, who had commanded them to worship idols and false gods.

15 : 18

هَٰٓؤُلَآءِ قَوۡمُنَا ٱتَّخَذُواْ مِن دُونِهِۦٓ ءَالِهَةٗۖ لَّوۡلَا يَأۡتُونَ عَلَيۡهِم بِسُلۡطَٰنِۭ بَيِّنٖۖ فَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ كَذِبٗا

15. These our people have taken (false) deities besides Him. Why do they not bring for (their worshiping of) them a clear authority? Who is then more unjust than he who invents a lie against Allāh?
