Al-Kahf 18:11

وَإِنَّا لَجَاعِلُونَ مَا عَلَيْهَا صَعِيدًا جُرُزًا

And indeed, We will make that which is upon it [into] a barren ground.

أَمْ حَسِبْتَ أَنَّ أَصْحَابَ الْكَهْفِ وَالرَّقِيمِ كَانُوا مِنْ آيَاتِنَا عَجَبًا

Or have you thought that the companions of the cave and the inscription were, among Our signs, a wonder?

إِذْ أَوَى الْفِتْيَةُ إِلَى الْكَهْفِ فَقَالُوا رَبَّنَا آتِنَا مِن لَّدُنكَ رَحْمَةً وَهَيِّئْ لَنَا مِنْ أَمْرِنَا رَشَدًا

[Mention] when the youths retreated to the cave and said, "Our Lord, grant us from Yourself mercy and prepare for us from our affair right guidance."

ثُمَّ بَعَثْنَاهُمْ لِنَعْلَمَ أَيُّ الْحِزْبَيْنِ أَحْصَىٰ لِمَا لَبِثُوا أَمَدًا

Then We awakened them that We might show which of the two factions was most precise in calculating what [extent] they had remained in time.

نَّحْنُ نَقُصُّ عَلَيْكَ نَبَأَهُم بِالْحَقِّ ۚ إِنَّهُمْ فِتْيَةٌ آمَنُوا بِرَبِّهِمْ وَزِدْنَاهُمْ هُدًى

It is We who relate to you, [O Muhammad], their story in truth. Indeed, they were youths who believed in their Lord, and We increased them in guidance.

وَرَبَطْنَا عَلَىٰ قُلُوبِهِمْ إِذْ قَامُوا فَقَالُوا رَبُّنَا رَبُّ السَّمَاوَاتِ وَالْأَرْضِ لَن نَّدْعُوَ مِن دُونِهِ إِلَـٰهًا ۖ لَّقَدْ قُلْنَا إِذًا شَطَطًا

And We made firm their hearts when they stood up and said, "Our Lord is the Lord of the heavens and the earth. Never will we invoke besides Him any deity. We would have certainly spoken, then, an excessive transgression.
