The Ka'ba's wall-paintings

Al-Mas'udi mentions that the walls of the Kaba, when Quraysh built it before the Prophethood, bore many images painted in various pigments. ²

• An image of Ibrahim with the divining arrows in his hand.
• Opposite it, an image of Ismail on a horse, conducting the people as they set out.
• An image called "al-Faruq," standing over a company of people and apportioning among them.
• About sixty further images of their descendants down to Qusayy ibn Kilab, each with the name of its owner, how he was worshipped, and what was known of his deeds.

When Quraysh completed the building, they put the images back and perfected their form and workmanship, according to al-Mas'udi. ²
