Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(56:17) immortal youths shall go about them *9

There will circulate among them young boys made eternal meaning

*9) This implies boys who will ever remain boys and stay young. Hadrat 'AIi and Hadrat Hasan Basri say that these will be those children of the people, who died before reaching their maturity; therefore, they will neither have any good works to their credit for which they may be rewarded, nor any evil deeds for which they may be punished, But obviously, this could imply those people who would not deserve Paradise. For, as for the true believers, about them Allah has guaranteed in the Qur'an that their children will be joined with them in Paradise (At-Tur: 21). This is also supported by the Hadith, which Abu Da'ud Tayalisi, Tabarani and Bazzar have related on the authority of Hadrat Anas and Hadrat Samurah bin Jundub, according to which the Holy Prophet (upon whom be Allah's peace) said that the children of the polytheists will be attendants of the people of Paradise. (For further explanation, see E.N. 26 of As-Saaffat, E.N. 19 of At-tur).
