It was narrated from ‘Aishah and Abu Hurairah that when the Messenger of Allah ﷺ wanted to offer a sacrifice, he brought two large, fat, horned, black-and-white, castrated rams. He slaughtered one on behalf of his nation, for whoever testified to Allah with monotheism and that he had conveyed (the Message), and he slaughtered the other on behalf of Muhammad and the family of Muhammad ﷺ. (Using translation from Ibn Mājah 3122)   

كَانَ رَسُولُ اللهِ ﷺ إِذَا ضَحَّى اشْتَرَى كَبْشَيْنِ عَظِيمَيْنِ سَمِينَيْنِ أَقْرَنَيْنِ أَمْلَحَيْنِ مَوْجُوئَيْنِ قَالَ فَيَذْبَحُ أَحَدَهُمَا عَنْ أُمَّتِهِ مِمَّنْ أَقَرَّ بِالتَّوْحِيدِ وَشَهِدَ لَهُ بِالْبَلَاغِ وَيَذْبَحُ الْآخَرَ عَنْ مُحَمَّدٍ وَآلِ مُحَمَّدٍ  

[Machine] The Prophet ﷺ used to bring two rams, both black and horned. He would slaughter one of them and say, "O Allah, this is on behalf of Muhammad and the family of Muhammad." Then he would bring the other ram and say, "O Allah, this is on behalf of my Ummah, to whoever testifies to Your Oneness and testifies to my prophethood."  

كَانَ النَّبِيُّ ﷺ يُقَرِّبُ كَبْشَيْنِ أَمْلَحَيْنِ فَيَذْبَحُ أَحَدَهُمَا فَيَقُولُ «اللهُمَّ هَذَا عَنْ مُحَمَّدٍ وَعَنْ آلِ مُحَمَّدٍ» وَقَرَّبَ الْآخَرَ فَقَالَ «اللهُمَّ هَذَا عَنْ أُمَّتِي لِمَنْ شَهِدَ لَكَ بِالتَّوْحِيدِ وَشَهِدَ لِي بِالْبَلَاغِ»  

[Machine] The Prophet ﷺ was brought two huge, dark, horned rams, so he laid down one of them and said, “In the name of Allah, and Allah is the greatest. O Allah, this is on behalf of Muhammad.” Then he laid down the other one and said, “In the name of Allah, and Allah is the greatest. O Allah, this is on behalf of Muhammad and his Ummah, from among those who have testified to Your oneness and testified to my Prophethood.” Then he slaughtered it.  

أَنَّ النَّبِيَّ ﷺ أُتِيَ بِكَبْشَيْنِ أَمْلَحَيْنِ أَقْرَنَيْنِ عَظِيمَيْنِ مَوْجُوءَيْنِ فَأَضْجَعَ أَحَدَهُمَا فَقَالَ بِسْمِ اللهِ وَاللهُ أَكْبَرُ اللهُمَّ هَذَا عَنْ مُحَمَّدٍ ثُمَّ أَضْجَعَ الْآخَرَ فَقَالَ بِسْمِ اللهِ وَاللهُ أَكْبَرُ اللهُمَّ هَذَا عَنْ مُحَمَّدٍ وَأُمَّتِهِ مِمَّنْ شَهِدَ لَكَ بِالتَّوْحِيدِ وَشَهِدَ لِي بِالْبَلَاغِ فَذَبَحَهُ

(Using translation from Ibn Mājah 3122)   

ؓ أَوْ أَبِي هُرَيْرَةَ ؓ الشَّكُّ مِنْ سُفْيَانَ قَالَ كَانَ رَسُولُ اللهِ ﷺ إِذَا ضَحَّى دَعَا بِكَبْشَيْنِ عَظِيمَيْنِ سَمِينَيْنِ أَمْلَحَيْنِ مُوجَأَيْنِ أَقْرَنَيْنِ فَذَبَحَ أَحَدَهُمَا عَنْ أُمَّتِهِ مَنْ شَهِدَ لَهُ بِالْبَلَاغِ وَشَهِدَ لِلَّهِ بِالتَّوْحِيدِ وَيَذْبَحُ الْآخَرَ عَنْ مُحَمَّدٍ وَآلِ مُحَمَّدٍ  

"اللَّهُمَّ هذا عن محمد وآل محمد، وقرب الآخر وقال: اللَّهُمَّ هذا عن أمتى لمن شهد لك بالتوحيد وشهد لي بالبلاغ" .
