Narrated Nafi`: Ibn `Umar. said, I have never missed the touching of these two stones of Ka`ba (the Black Stone and the Yemenite Corner) both in the presence and the absence of crowds, since I saw the Prophet touching them. I asked Nafi`: Did Ibn `Umar use to walk between the two Corners? Nafi` replied, He used to walk in order that it might be easy for him to touch it (the Corner Stone).
