At-Tur - 52:24

وَيَطُوفُ عَلَيْهِمْ غِلْمَانٌ لَّهُمْ كَأَنَّهُمْ لُؤْلُؤٌ مَّكْنُونٌ
[52:24]
And round them shall go boys of theirs as if they were hidden pearls.
Round about them will serve, (devoted) to them, young male servants (handsome) as Pearls well-guarded.
And there go round, waiting on them menservants of their own, as they were hidden pearls.
