Salim bin Abdullah narrates from his father (Sayyiduna Abdullah bin Umar, may Allah be pleased with them both): Sayyiduna Umar bin Khattab, may Allah be pleased with him, kissed the Black Stone and said: By Allah! I know that you are a stone; if I had not seen the Prophet Muhammad (peace and blessings of Allah be upon him) kissing you, I would not have kissed you.
