[Machine] I reached the Prophet ﷺ on the day of Arafat, and he said while speaking: "Do you know it?" He said, "I do not know what they have returned to." The Prophet ﷺ then said, "It is incumbent upon the people of every household to sacrifice a sheep in every Rajab and a sheep in every Eid Al-Adha."  

انْتَهَيْتُ إِلَى النَّبِيِّ ﷺ يَوْمَ عَرَفَةَ قَالَ وَهُوَ يَقُولُ هَلْ تَعْرِفُونَهَا؟ قَالَ فَمَا أَدْرِي مَا رَجَعُوا عَلَيْهِ قَالَ فَقَالَ النَّبِيُّ ﷺ عَلَى أَهْلِ كُلِّ بَيْتٍ أَنْ يَذْبَحُوا شَاةً فِي كُلِّ رَجَبٍ وَكُلِّ أَضْحَى شَاةً  

“We were standing with the Prophet ﷺ at ‘Arafat and he said: ‘O people, each family, each year, must offer Udhiyah and ‘Atirah.’ (Using translation from Ibn Mājah 3125)  

وَنَحْنُ وُقُوفٌ مَعَ النَّبِيِّ ﷺ بِعَرَفَةَ فَقَالَ يَا أَيُّهَا النَّاسُ إِنَّ عَلَى أَهْلِ كُلِّ بَيْتٍ فِي كُلِّ عَامٍ أَضْحَاةً وَعَتِيرَةً أَتَدْرُونَ مَا الْعَتِيرَةُ؟ هِيَ الَّتِي يُسَمِّيهَا النَّاسُ الرَّجَبِيَّةُ
