I offered the ʿId prayer with Messenger of Allah ﷺ, Abu Bakr, ʿUmar and ʿUthman and all of them offered the prayer before delivering the Khutba.  

شَهِدْتُ الْعِيدَ مَعَ رَسُولِ اللَّهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ ؓ فَكُلُّهُمْ كَانُوا يُصَلُّونَ قَبْلَ الْخُطْبَةِ  

[Machine] I saw the Prophet ﷺ on the day of Eid, he started praying before the sermon without an Adhan or Iqamah.  

شَهِدْتُ النَّبِيَّ ﷺ فِي يَوْمِ عِيدٍ بَدَأَ بِالصَّلَاةِ قَبْلَ الْخُطْبَةِ بِغَيْرِ أَذَانٍ وَلَا إِقَامَةٍ  

[Machine] The Prophet Muhammad ﷺ prayed, then Abu Bakr, Umar, and Uthman delivered speeches on the day of Eid without giving adhan or iqamah.  

صَلَّى رَسُولُ اللهِ ﷺ ثُمَّ خَطَبَ وَأَبُو بَكْرٍ وَعُمَرُ وَعُثْمَانُ فِي الْعِيدِ بِغَيْرِ أَذَانٍ وَلَا إِقَامَةٍ  

I observed prayer with the Messenger of Allah ﷺ on the 'Id day. He commenced with prayer before the sermon without Adhan and Iqama. He then stood up leaning on Bilal, and he commanded (them) to be on guard (against evil for the sake of) Allah, and he exhorted (them) on obedience to Him, and he preached to the people and admonished them. He then walked on till he came to the women and preached to them and admonished them, and asked them to give alms, for most of them are the fuel for Hell. A woman having a dark spot on the cheek stood up and said: Why is it so, Messenger of Allah? He said: For you grumble often and show ingratitude to your spouse. And then they began to give alms out of their ornaments such as their earrings and rings which they threw on to the cloth of Bilal. (Using translation from Muslim 885b)  

«شَهِدْتُ الصَّلَاةَ مَعَ رَسُولِ اللَّهِ ﷺ فِي يَوْمِ عِيدٍ فَبَدَأَ بِالصَّلَاةِ قَبْلَ الْخُطْبَةِ بِغَيْرِ أَذَانٍ وَلَا إِقَامَةٍ»  

[Machine] "I witnessed the Prophet, peace be upon him, and Abu Bakr, Umar, and Uthman praying before the sermon on the day of Eid."  

«شَهِدْتُ النَّبِيَّ ﷺ وَأَبَا بَكْرٍ وَعُمَرَ وَعُثْمَانَ يُصَلُّونَ قَبْلَ الْخُطْبَةِ فِي الْعِيدِ»
