It was narrated from Ibn 'Abbas that 'Umar bin al-Khattab رضي الله عنه held onto the corner of the Ka'bah and said:
I know that you are only a stone; if I had not seen my Beloved kiss you or touch you, I would not have touched you or kissed you. “Indeed in the Messenger of Allah (Muhammad ﷺ) you have a good example to follow” (al-Ahzab 33:21].
