يَطُوفُ عَلَيْهِمْ وِلْدَٰنٌ مُّخَلَّدُونَ Qur’an Al-Waqia (56:17)Yatoofu AAalayhim wildanun mukhalladoona
Cf. lii. 24, and n. 5058. The youth and freshness with which the attendants will serve is a symbol of true service such as we may expect in the next world. That freshness will be perpetual, and not subject to any moods, or chances, or changes.
