‘Umar ibn al-Khattāb, Commander of the Believers, (may Allah be pleased with him) came to the Black Stone in the corner of the Ka‘bah and kissed it. He, then, said: Verily, I know that you are a stone that can neither harm nor benefit. Had I not seen the Prophet (may Allah's peace and blessings be upon him) kissing you, I would not have kissed you.
