Narrated `Abdul-Aziz bin Rufai:
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا إِسْحَاقُ بْنُ يُوسُفَ ، حَدَّثَنَا سُفْيَانُ الثَّوْرِيُّ ، عَنْ عَبْدِ الْعَزِيزِ بْنِ رُفَيْعٍ ، قَالَ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ أَخْبِرْنِي بِشَىْءٍ، عَقَلْتَهُ عَنِ النَّبِيِّ صلى الله عليه وسلم أَيْنَ صَلَّى الظُّهْرَ يَوْمَ التَّرْوِيَةِ قَالَ بِمِنًى. قُلْتُ فَأَيْنَ صَلَّى الْعَصْرَ يَوْمَ النَّفْرِ قَالَ بِالأَبْطَحِ. افْعَلْ كَمَا يَفْعَلُ أُمَرَاؤُكَ.
I asked Anas bin Malik, "Tell me something you have observed about the Prophet (ﷺ) concerning where he offered the Zuhr prayer on the Day of Tarwiya (8th Dhul-Hijja)." Anas replied, "He offered it at Mina." I said, "Where did he offer the `Asr prayer on the Day of Nafr (day of departure from Mina)?" He replied, "At Al-Abtah," and added, "You should do as your leaders do."
