Sunan Abi Dawud 673
Narrated 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 Messenger of Allah (ﷺ).
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا سُفْيَانُ، عَنْ يَحْيَى بْنِ هَانِئٍ، عَنْ عَبْدِ الْحَمِيدِ بْنِ مَحْمُودٍ، قَالَ صَلَّيْتُ مَعَ أَنَسِ بْنِ مَالِكٍ يَوْمَ الْجُمُعَةِ فَدُفِعْنَا إِلَى السَّوَارِي فَتَقَدَّمْنَا وَتَأَخَّرْنَا فَقَالَ أَنَسٌ كُنَّا نَتَّقِي هَذَا عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
