It is narrated from Hazrat Urwah bin Zubair that Sayyiduna Umar bin Khattab, may Allah be pleased with him, said while he was performing tawaf of the Ka'bah, to the Black Stone: You are a stone, you can neither benefit nor harm, and if I had not seen the Messenger of Allah, peace and blessings be upon him, kissing you, I would not have kissed you. Then he kissed the Black Stone.

Imam Malik, may Allah have mercy on him, said: I heard from some people of knowledge that when one touches the Yemeni Corner and raises his hand, he should place his hand on his mouth but should not kiss it.
