narrated by Zaid bin Aslam (رضئ اللہ تعالی عنہ) from his father who said: "Umar bin Al-Khattab (رضئ اللہ تعالی عنہ) addressed the Corner (Black Stone) saying, 'By Allah(سبحانہ و تعا لی) ! I know that you are a stone and can neither benefit nor harm. Had I not seen the Prophet (صلى الله عليه و آله وسلم) touching, I would never have touched (and kissed) you.' Then he kissed it and said, 'There is no reason for us to do Ramal (during circumambulating - Tawaf) except that we wanted to show off before the Pagans, and now Allah (سبحانہ و تعا لی) has destroyed them.' 'Umar (رضئ اللہ تعالی عنہ) added, '(nevertheless), the Prophet (صلى الله عليه و آله وسلم) did that and we do not want to leave it (i.e. Ramal).' (Bukhari book #26, Hadith #675).
