[Machine] He ﷺ prayed for the people on the day of sacrifice. When he finished his sermon and prayer, he called for a sheep and slaughtered it himself, saying, "In the name of Allah, Allah is the Greatest. O Allah, this is from me and from those who did not sacrifice from my Ummah." This narration is reported by Abu Sa'id Al-Khudri, Abu Hurairah, and Anas bin Malik from the Prophet ﷺ in its meaning. Al-Shafi'i (may Allah have mercy on him) said that we were informed that Abu Bakr and Umar (may Allah be pleased with them) disliked being followed in this matter, so whoever saw them may assume that it is not obligatory.  

ﷺ صَلَّى لِلنَّاسِ يَوْمَ النَّحْرِ فَلَمَّا فَرَغَ مِنْ خُطْبَتِهِ وَصَلَاتِهِ دَعَا بِكَبْشٍ فَذَبَحَهُ هُوَ بِنَفْسِهِ وَقَالَ بِسْمِ اللهِ وَاللهُ أَكْبَرُ اللهُمَّ عَنِّي وَعَمَّنْ لَمْ يُضَحِّ مِنْ أُمَّتِي وَرُوِيَ ذَلِكَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ وَأَبِي هُرَيْرَةَ وَأَنَسِ بْنِ مَالِكٍ ؓ عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ وَبَلَغَنَا أَنَّ أَبَا بَكْرٍ الصِّدِّيقَ وَعُمَرَ ؓ كَانَا لَا يُضَحِّيَانِ كَرَاهِيَةَ أَنْ يُقْتَدَى بِهِمَا فَيَظُنُّ مَنْ رَآهُمَا أَنَّهَا وَاجِبَةٌ
