I observed Id along with Umar b. al-Khattab (Allah be pleased with him). He came (out in an open space) and prayed and (after) completing it addressed the people and said: The Messenger of Allah ﷺ has forbidden the observing of fast on these two days. One is the day of Fitr (at the end of your fasts), and the second one, the day when you eat (the meat) of your sacrifices.  

إِنَّ هَذَيْنِ يَوْمَانِ نَهَى رَسُولُ اللَّهِ ﷺ عَنْ صِيَامِهِمَا يَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَالْآخَرُ يَوْمٌ تَأْكُلُونَ فِيهِ مِنْ نُسُكِكُمْ  

I attended the 'Id (prayer) along with 'Umar. He offered prayer before the sermon. He then said: The Messenger of Allah ﷺ prohibited fasting on these two days. As regards Id al-Adha, you eat the meat of your sacrificial animals. As for 'Id al-Fitr, you break (i.e. end) your fast.  

شَهِدْتُ الْعِيدَ مَعَ عُمَرَ فَبَدَأَ بِالصَّلاَةِ قَبْلَ الْخُطْبَةِ ثُمَّ قَالَ إِنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْ صِيَامِ هَذَيْنِ الْيَوْمَيْنِ أَمَّا يَوْمُ الأَضْحَى فَتَأْكُلُونَ مِنْ لَحْمِ نُسُكِكُمْ وَأَمَّا يَوْمُ الْفِطْرِ فَفِطْرُكُمْ مِنْ صِيَامِكُمْ  

I attended Eid with ʿUmar bin al-Khattab, He came and prayed, then he stood and addressed the people saying: These are two days when the Messenger of Allah ﷺ forbade fasting, the day when you break your fast and the other day, when you eat from your sacrifices.  

إِنَّ هَذَيْنِ يَوْمَانِ نَهَى رَسُولُ اللهِ ﷺ عَنْ صِيَامِهِمَا يَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَالْآخَرُ يَوْمٌ تَأْكُلُونَ فِيهِ مِنْ نُسُكِكُمْ  

O people, the Messenger of Allah ﷺ forbade fasting on these two days (i.e., the two Eids). On the first of them you break your fast and celebrate your festival, and on the second you eat from the meat of your sacrifices. It was narrated that Sa'd Abu 'Ubaid, the freed slave of ‘Abdur-Rahman bin Azhar, said: I was present at Eid with 'Umar bin al Khattab... and he mentioned a similar hadeeth.  

أَنْ يَخْطُبَ بِلا أَذَانٍ وَلا إِقَامَةٍ ثُمَّ خَطَبَ فَقَالَ يَا أَيُّهَا النَّاسُ إِنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ صِيَامِ هَذَيْنِ الْيَوْمَيْنِ أَمَّا أَحَدُهُمَا فَيَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَعِيدُكُمْ وَأَمَّا الْآخَرُ فَيَوْمٌ تَأْكُلُونَ فِيهِ مِنْ نُسُكِكُمْ  

[Machine] Verily, the Messenger of Allah ﷺ prohibited fasting these two days: the day of your breaking the fast from your fasting, and the other day when you partake in your rituals.  

إِنَّ هَذَيْنِ يَوْمَانِ نَهَى رَسُولُ اللهِ ﷺ عَنْ صِيَامِهِمَا يَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَالْآخَرُ يَوْمٌ تَأْكُلُونَ فِيهِ مِنْ نُسُكِكُمْ  

I was present at Eid with ‘Umar, and he started with the prayer before the khutbah. He said: The Messenger of Allah ﷺ forbade fasting on these two days. The day of al-Fitr is the day when you break your fast, and on the day of al-Adha, eat the meat of your sacrifices. (Using translation from Aḥmad 163)   

شَهِدْتُ الْعِيدَ مَعَ عُمَرَ ؓ فَبَدَأَ بِالصَّلَاةِ قَبْلَ الْخُطْبَةِ ثُمَّ قَالَ إِنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ صِيَامِ هَذَيْنِ الْيَوْمَيْنِ أَمَّا يَوْمُ الْأَضْحَى فَتَأْكُلُونَ مِنْ نُسُكِكُمْ وَأَمَّا يَوْمُ الْفِطْرِ فَفِطْرُكُمْ مِنْ صِيَامِكُمْ  

" (عن أبي عبيد قال: شهدت العيد مع عمر بن الخطاب، فبدأ بالصلاة قبل الخطبة فقال) (*): إن رسولَ الله ﷺ نهى عن صيامِ هذَين اليومينِ: يومِ الفطرِ ويومِ الأضحى، أما يومُ الفطرِ فيومُ فِطرِكم من صومِكم، وأما يوْمُ الأضحى فكُلوا فيه من لحمِ نَسُكِكم" .
