(the slave of Ibn Azhar) I witnessed the ʿId with ʿUmar bin Al-Khattab who said, Messenger of Allah ﷺ has forbidden people to fast on the day on which you break fasting (the fasts of Ramadan) and the day on which you eat the meat of your sacrifices (the first day of ʿId ul Fitr and ʿId ul-Adha).  

شَهِدْتُ الْعِيدَ مَعَ عُمَرَ بْنِ الْخَطَّابِ ؓ فَقَالَ: هَذَانِ يَوْمَانِ نَهَى رَسُولُ اللَّهِ ﷺ عَنْ صِيَامِهِمَا يَوْمُ فِطْرِكُمْ مِنْ صِيَامِكُمْ وَالْيَوْمُ الآخَرُ تَأْكُلُونَ فِيهِ مِنْ نُسُكِكُمْ۔  

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  

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 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»  

[Machine] "O people, indeed the Messenger of Allah ﷺ forbade fasting on these two days. As for one of them, it is the day of your Eid and the day of breaking your fast, and as for the other, it is a day in which you eat from your sacrifices."  

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
