Salim reports that his father, Sayyiduna Abdullah bin Umar (may Allah be pleased with them), informed him that Sayyiduna Umar (may Allah be pleased with him) kissed the Black Stone, then said: By Allah! I know that you are a stone. If I had not seen the Messenger of Allah (peace and blessings be upon him) kissing you, I would never have kissed you. Amr says: Zayd bin Aslam also narrated to me a similar report from his father.
