Abu Dawud Book 2, Hadith Number 673.

Narated By AbdulHamid ibn Mahmud : I offered the Friday prayer along with Anas ibn Malik. We were pushed to the pillars (due to the crowd of people). We, therefore, stopped forward and backward. Anas then said: We used to avoid it (setting a row between the pillars) during the time of the Apostle of Allah (PBUH).
