Al-Insan 19

۞ وَيَطُوفُ عَلَيْهِمْ وِلْدَٰنٌ مُّخَلَّدُونَ إِذَا رَأَيْتَهُمْ حَسِبْتَهُمْ لُؤْلُؤًا مَّنثُورًا

wayaṭūfu ʿalayhim wil'dānun mukhalladūna idhā ra-aytahum ḥasib'tahum lu'lu-an manthūran

There will circulate among them young boys made eternal. When you see them, you would think them [as beautiful as] scattered pearls.
