"I heard Ibn 'Abbas say: 'I bear witness that I attended 'Eid with the Messenger of Allah ﷺ; he started with the prayer before the Khutbah, then he delivered the Khutbah.'"  

سَمِعْتُ ابْنَ عَبَّاسٍ يَقُولُ أَشْهَدُ أَنِّي شَهِدْتُ الْعِيدَ مَعَ رَسُولِ اللَّهِ ﷺ فَبَدَأَ بِالصَّلاَةِ قَبْلَ الْخُطْبَةِ ثُمَّ خَطَبَ  

"The Messenger of Allah ﷺ addressed us on the day of An-Nahr after the prayer." (Sahih  

خَطَبَنَا رَسُولُ اللَّهِ ﷺ يَوْمَ النَّحْرِ بَعْدَ الصَّلاَةِ
