Musnad Abu Ya'la al-Mawsili 42:432

From Abu Sa'id al-Khudri, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, the person of the lowest status among the people of Paradise is he who has eighty thousand servants and seventy-two wives. A dome of pearl, chrysolite, and emerald is set up for him, [the size of which is] as the distance between al-Jabiyah and San'a."
