I heard the Prophet ﷺ delivering a sermon at ʿArafat.  

البخاري:١٧٤٠حَدَّثَنَا حَفْصُ بْنُ عُمَرَ حَدَّثَنَا شُعْبَةُ قَالَ أَخْبَرَنِي عَمْرٌو قَالَ سَمِعْتُ جَابِرَ بْنَ زَيْدٍ قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ ؓ قَالَ

سَمِعْتُ النَّبِيَّ ﷺ يَخْطُبُ بِعَرَفَاتٍ  

تَابَعَهُ ابْنُ عُيَيْنَةَ عَنْ عَمْرٍو
