Muwatta Malik, Book 20, Hadith 851 (In-Book) ⓘ
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "A sacrificial animal is what has been garlanded, branded, and stood with on Arafa."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَقُولُ الْهَدْىُ مَا قُلِّدَ وَأُشْعِرَ وَوُقِفَ بِهِ بِعَرَفَةَ .
