A man asked Ibb 'Abbas: Have you been present along with the Messenger of Allah ﷺ ? He replied: Yes. Had there been no dignity for me in his eyes, I would not have been present with him due to my minority. Then the Messenger of Allah ﷺ came to the point that was near the house of Kathir b. al-Salt. He prayed and afterwards preached. He (Ibn 'Abbas) did not mention the adhan (call to prayer) and the iqamah. He then commanded to give alms. The women began to point to their ears and throats (to give their jewelry in alms).  

سَأَلَ رَجُلٌ ابْنَ عَبَّاسٍ أَشَهِدْتَ الْعِيدَ مَعَ رَسُولِ اللَّهِ ﷺ قَالَ نَعَمْ وَلَوْلاَ مَنْزِلَتِي مِنْهُ مَا شَهِدْتُهُ مِنَ الصِّغَرِ فَأَتَى رَسُولُ اللَّهِ ﷺ الْعَلَمَ الَّذِي عِنْدَ دَارِ كَثِيرِ بْنِ الصَّلْتِ فَصَلَّى ثُمَّ خَطَبَ وَلَمْ يَذْكُرْ أَذَانًا وَلاَ إِقَامَةً قَالَ ثُمَّ أَمَرَ بِالصَّدَقَةِ قَالَ فَجَعَلَ النِّسَاءُ يُشِرْنَ إِلَى آذَانِهِنَّ وَحُلُوقِهِنَّ قَالَ فَأَمَرَ بِلاَلاً فَأَتَاهُنَّ ثُمَّ رَجَعَ إِلَى النَّبِيِّ ﷺ  

The Messenger of Allah ﷺ offered the 'Id prayer without the adhan and the iqamah. AbuBakr and Umar or Uthman also did so. The narrator Yahya is doubtful about Uthman.  

أَنَّ رَسُولَ اللَّهِ ﷺ صَلَّى الْعِيدَ بِلاَ أَذَانٍ وَلاَ إِقَامَةٍ وَأَبَا بَكْرٍ وَعُمَرَ أَوْ عُثْمَانَ شَكَّ يَحْيَى  

I prayed the 'Id prayer with the Prophet ﷺ not once or twice (but many times) without the adhan and the iqamah.  

صَلَّيْتُ مَعَ النَّبِيِّ ﷺ غَيْرَ مَرَّةٍ وَلاَ مَرَّتَيْنِ الْعِيدَيْنِ بِغَيْرِ أَذَانٍ وَلاَ إِقَامَةٍ
