The People of Paradise will be served by boys whom Allah (swt) will create to serve them and who will be most beautiful and perfect in form:

“They will be served by immortal boys, With cups, and jugs, and a glass from the flowing wine.” [56:17-18]

“And round about them will [serve] boys of everlasting youth. If you see them, you would think them scattered pearls.” [76:19]

Ibn Katheer, may Allah have mercy on him, said, “Boys of eternal youth will go around to serve people of Paradise, boys who remain in that youthful form forever, never changing or advancing in age. It was said that they will be wearing earrings, to emphasise their youth, because such a thing is appropriate for young people, but it does not befit those who are older. And Allah (swt) said [76:19] i.e. if you saw them going around to attend to the needs of their masters, with their beautiful faces and splendid colorful clothes and jewellery, you would think that they were scattered pearls. There is no more beautiful description than the picture of pearls scattered in a place of beauty.” [Tafseer Ibn Katheer, 7/184]

Some scholars suggested that these boys are the children of the Muslims and Mushrikeen who die in childhood, but this was refuted by al-‘Allaamah Ibn Taymiyyah (ra), who explained that these boys of eternal youth are part of the creation of Paradise: “..they are not the children of this world. When the children of this world enter Paradise, they will do so in a perfect form, like all the other people of Paradise, in the form of their father, Aadam.” [Majmu’ al-Fatawa, 4/279, 4/311]
