كتاب الفرع والعتيرة
Read the English translation first, with the original Arabic directly underneath.
Mikhnaf bin Sulaim said:
"While we were standing with the Messenger of Allah at 'Arafat, he said: 'O people, it is upon each family to offer a sacrifice (Udhiyah) and an 'Atirah each year." (One of the narrators) Muadh said: "Ibn 'Awn used to offer slaughter the 'Atirah, and I saw that with my own eyes during Rajab." (Daif)
يَا أَيُّهَا النَّاسُ إِنَّ عَلَى أَهْلِ بَيْتٍ فِي كُلِّ عَامٍ أَضْحَاةً وَعَتِيرَةً
