Ibn ‘Umar said that he had not seen the Prophet touching anything in the House but the two Yamani corners (The corner containing the Black Stone and the Yamani corner to the south-east which, as is usually held, should be touched but not kissed. They are both held to be on the foundations laid by Abraham).
He said that God’s messenger went round the House on a camel, and as often as he came to the corner he pointed to it with something in his hand and said, “God is most great.”
Az-Zubair b. ‘Arabi said that a man asked Ibn ‘Umar about touching the stone, and he replied that he had seen God s messenger touching it and kissing it.
