Safiyyah bint Shaybah (may Allah be pleased with her) says: When the Messenger of Allah (peace and blessings be upon him) had settled in Makkah in the year of the Conquest, he (peace and blessings be upon him) performed the tawaf riding on his camel, touching the Black Stone with the staff in his hand. Then he entered the Ka'bah. He found in it a dove made of wood, and he broke it. Then he took it to the door of the Ka'bah and threw it away, while I was watching.
