Sunan Abi Dawud 1912

‘Abd Al ‘Aziz bin Rufai’ said I asked Anas bin Malik saying “Tell me something you knew about the Apostle of Allaah(ﷺ) viz where he offered the noon prayer on Yawm Al Tarwiyah(8th of Dhu Al Hijjah). He replied, In Mina I asked Where did he pray the afternoon prayer on Yaum Al Nafr(12th or 13th of Dhu Al Hijjah). He replied In al-Abtah he then said “Do as your commanders do.”
