Musannaf Ibn Abi Shaybah 36695 — Reports on the description

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said that a woman from the women of Paradise will wear seventy garments of silk, and through them the whiteness of her shin and the beauty of her shin will be visible, and the marrow of her shin will also be fully visible through them. This is because Allah has said: "As though they were rubies and coral." [Al-Rahman: 58] A ruby is only a stone; if you take a thread, put it into that stone, and then polish it clear, you will see that thread from behind the stone.
