Surah Al-Kahf — Ayah 13 (18:13)
نَّحۡنُ نَقُصُّ عَلَيۡكَ نَبَأَهُم بِٱلۡحَقِّۚ إِنَّهُمۡ فِتۡيَةٌ ءَامَنُواْ بِرَبِّهِمۡ وَزِدۡنَٰهُمۡ هُدٗى ١٣
English translation (Saheeh International)
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.
Brief commentary
I am informing you, O Messenger, of their affair, truthfully without any doubt. Surely, they were youngsters who believed in their Lord and obeyed Him, and I increased them in guidance and firmness on the truth.
