Musnad Ahmad 31:138

Yahya ibn Adam narrated to us, Fudayl narrated to us, from Atiyyah, Abu Sa’id al-Khudri narrated to us, he said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "Indeed, the first group to enter Paradise on the Day of Resurrection, the form of their faces will be like the form of the moon on the night of the full moon. The second group will be of a color more beautiful than a brilliant star in the sky. For every man among them will be two wives; upon each wife will be seventy garments, and the marrow of her shin will be seen from behind her flesh, her blood, and her garments."
