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  

Messenger of Allah ﷺ, Abu Bakr and ʿUmar! used to offer the two ʿId prayers before delivering the Khutba.  

كَانَ رَسُولُ اللَّهِ ﷺ وَأَبُو بَكْرٍ وَعُمَرُ ؓ يُصَلُّونَ الْعِيدَيْنِ قَبْلَ الْخُطْبَةِ  

The Prophet ﷺ offered a two rakʿat prayer on the Day of Id ul Fitr and he did not pray before or after it. Then he went towards women along with Bilal and ordered them to pay alms and so they started giving their earrings and necklaces (in charity).  

أَنَّ النَّبِيَّ ﷺ صَلَّى يَوْمَ الْفِطْرِ رَكْعَتَيْنِ لَمْ يُصَلِّ قَبْلَهَا وَلاَ بَعْدَهَا ثُمَّ أَتَى النِّسَاءَ وَمَعَهُ بِلاَلٌ فَأَمَرَهُنَّ بِالصَّدَقَةِ فَجَعَلْنَ يُلْقِينَ تُلْقِي الْمَرْأَةُ خُرْصَهَا وَسِخَابَهَا  

The Prophet ﷺ said, "The first thing that we should do on this day of ours is to pray and then return to slaughter the sacrifice. So anyone who does so, he acted according to our Sunna (tradition), and whoever slaughtered the sacrifice before the prayer, it was just meat which he presented to his family and would not be considered as Nusuk." A person from the Ansar named Abu Burda bin Niyyar said, "O Messenger of Allah ﷺ! I slaughtered the Nusuk (before the prayer) but I have a young shegoat which is better than an older sheep." The Prophet ﷺ I said, "Sacrifice it in lieu of the first, but it will be not sufficient (as a sacrifice) for anybody else after you."  

قَالَ النَّبِيُّ ﷺ إِنَّ أَوَّلَ مَا نَبْدَأُ فِي يَوْمِنَا هَذَا أَنْ نُصَلِّيَ ثُمَّ نَرْجِعَ فَنَنْحَرَ فَمَنْ فَعَلَ ذَلِكَ فَقَدْ أَصَابَ سُنَّتَنَا وَمَنْ نَحَرَ قَبْلَ الصَّلاَةِ فَإِنَّمَا هُوَ لَحْمٌ قَدَّمَهُ لأَهْلِهِ لَيْسَ مِنَ النُّسْكِ فِي شَىْءٍ فَقَالَ رَجُلٌ مِنَ الأَنْصَارِ يُقَالُ لَهُ أَبُو بُرْدَةَ بْنُ نِيَارٍ يَا رَسُولَ اللَّهِ ذَبَحْتُ وَعِنْدِي جَذَعَةٌ خَيْرٌ مِنْ مُسِنَّةٍ فَقَالَ اجْعَلْهُ مَكَانَهُ وَلَنْ تُوفِيَ أَوْ تَجْزِيَ عَنْ أَحَدٍ بَعْدَكَ
