Surah Al-Kahf, verse 11

أَمْ حَسِبْتَ أَنَّ أَصْحَـٰبَ ٱلْكَهْفِ وَٱلرَّقِيمِ كَانُوا۟ مِنْ ءَايَـٰتِنَا عَجَبًا ﴿٩﴾

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

إِذْ أَوَى ٱلْفِتْيَةُ إِلَى ٱلْكَهْفِ فَقَالُوا۟ رَبَّنَآ ءَاتِنَا مِن لَّدُنكَ رَحْمَةًۭ وَهَيِّئْ لَنَا مِنْ أَمْرِنَا رَشَدًۭا ﴿١٠﴾

[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 بَعَثْنَـٰهُمْ لِنَعْلَمَ أَىُّ ٱلْحِزْبَيْنِ أَحْصَىٰ لِمَا لَبِثُوٓا۟ أَمَدًۭا ﴿١٢﴾

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 بِٱلْحَقِّ ۚ إِنَّهُمْ فِتْيَةٌ ءَامَنُوا۟ بِرَبِّهِمْ وَزِدْنَـٰهُمْ هُدًۭى ﴿١٣﴾

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