How authentic is the Hadith: "The people of Paradise will enter Paradise at the height of Adam, sixty cubits by the cubit of the King, with the beauty of Joseph, at the age of Jesus: thirty-three years old, and with the tongue of Muhammad, beardless, of slight build, and with kohl-rimmed eyes"? And what is its explanation, especially the phrases: "by the cubit of the King", "at the age of Jesus", and "with the tongue of Muhammad, may Allah’s prayers and peace be upon him"?

This Hadith has been narrated through several chains, some of which have been deemed sound by scholars. Among them is what is reported in the Two Sahihs and other collections, on the authority of Abu Hurayrah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "The people of Paradise will enter Paradise hairless, beardless, fair-skinned, with kohl-lined eyes, at the age of thirty-three, resembling Adam in creation, sixty cubits tall and seven cubits wide."

As for its meaning: They will be at the peak of their youth (33 years old), possessing a high degree of beauty and handsomeness, and they will speak Arabic. As for the cubit, it is said to be the cubit of a great king, or the king of Yemen known as "Al-Jabbar," who was enormous in stature and height. This is how some scholars have interpreted it, citing the Hadith: "Indeed, the thickness of the disbeliever's skin will be forty-two cubits by the cubit of Al-Jabbar, and his molar tooth will be like Uhud." And Allah knows best.
