The Prophet ﷺ went out and offered a two rakʿat prayer on the Day of ʿId ul Fitr and did not offer any other prayer before or after it and at that time Bilal was accompanying him.  

أَنَّ النَّبِيَّ ﷺ خَرَجَ يَوْمَ الْفِطْرِ فَصَلَّى رَكْعَتَيْنِ لَمْ يُصَلِّ قَبْلَهَا وَلاَ بَعْدَهَا وَمَعَهُ بِلاَلٌ
