Surah Al-Insan, ayah 19

۞ وَيَطُوفُ عَلَيۡهِمۡ وِلۡدَٰنٞ مُّخَلَّدُونَ إِذَا رَأَيۡتَهُمۡ حَسِبۡتَهُمۡ لُؤۡلُؤٗا مَّنثُورٗا ١٩

Wayatūfu 'alayhim wildānum mukhalladūna idhā ra'aytahum hasibtahum lu'lu'am manthūrā

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