It was narrated that Ibn Umar said: "We left for Arafat with the Messenger of Allah, and some of us were reciting the Talbiyah and some reciting the Takbir."
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ، قَالَ حَدَّثَنَا هُشَيْمٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي سَلَمَةَ، عَنِ ابْنِ عُمَرَ، قَالَ غَدَوْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِلَى عَرَفَاتٍ فَمِنَّا الْمُلَبِّي وَمِنَّا الْمُكَبِّرُ .
