﴿ نَّحْنُ نَقُصُّ عَلَيْكَ نَبَأَهُم بِٱلْحَقِّ ۚ إِنَّهُمْ فِتْيَةٌ ءَامَنُوا۟ بِرَبِّهِمْ وَزِدْنَٰهُمْ هُدًۭى ﴾

“[And now] We shall truly relate to thee their story: Behold, they were young men who had attained to faith in their Sustainer: and [so] We deepened their consciousness of the right way”

(We narrate unto thee) We exposit to you (their story with truth. Lo! they were young men who believed in their Lord, and We increased them in guidance) in insight into the matter of their religion; it is also said that this means: We made them firm in their faith.
