Sura 18 Al-Kahf (The Cave), aya 13

1. نَحْنُ نَقُصُّ عَلَيْكَ نَبَأَهُمْ 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.
