the freed slave of Ibn Azhar that he witnessed the Day of ʿId-al-Adha with ʿUmar bin Al-Khattab. ʿUmar offered the ʿId prayer before the sermon and then delivered the sermon before the people, saying, "O people! Messenger of Allah ﷺ has forbidden you to fast (on the first day of) each of these two 'Ida, for one of them is the Day of breaking your fast, and the other is the one, on which you eat the meat of your sacrifices."  

يَا أَيُّهَا النَّاسُ إِنَّ رَسُولَ اللَّهِ ﷺ قَدْ نَهَاكُمْ عَنْ صِيَامِ هَذَيْنِ الْعِيدَيْنِ أَمَّا أَحَدُهُمَا فَيَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَأَمَّا الآخَرُ فَيَوْمٌ تَأْكُلُونَ نُسُكَكُمْ  

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
