.Regarding the black stone, Hajr-e-Aswad, Umar the illustrious companion of the Prophet Muhammed (peace be upon him), said:"I know that you are a stone and can neither benefit nor harm. Had I not seen the Prophet (peace be upon him) touching (and kissing) you, I would never have touched (and kissed) you".[Sahih Bukhari, Volume 2, Chapter 56, Tradition No. 675].Thus, it is important to note that though Muslims face the Kaaba during prayers, they do not worship the Kaaba. Muslims worship and bow to none but Allah.
