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  

“I was present for ‘Eid with ‘Umar bin Khattab. He started with the prayer before the sermon, and said: ‘The Messenger of Allah ﷺ forbade fasting on these two days, the Day of Fitr and the Day of Adha. As for the Day of Fitr, it is the day when you break your fast, and on the Day of Adha you eat the meat of your sacrifices.’” (Using translation from Ibn Mājah 1722)   

إِنَّ رَسُولَ اللهِ ﷺ «نَهَى عَنْ صِيَامِ هَذَيْنِ الْيَوْمَيْنِ أَمَّا يَوْمُ الْفِطْرِ فَيَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَأَمَّا يَوْمُ الْأَضْحَى فَيَوْمُ نُسُكِكُمْ»  

" (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" .
