The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
Dawud :: Book 10 : Hadith 1882
Narrated Umar ibn al-Khattab:
Aslam said: I heard Umar ibn al-Khattab say: What is the need of walking proudly (ramal) and moving the shoulders (while going round the Ka'bah)? Allah has now strengthened Islam and obliterated disbelief and the infidels. In spite of that we shall not forsake anything that we used to do during the time of the Apostle of Allah (peace_be_upon_him).
