مُوَطَّأُ مَالِكٍ
Muwatta Malik 851
Hajj
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَقُولُ الْهَدْىُ مَا قُلِّدَ وَأُشْعِرَ وَوُقِفَ بِهِ بِعَرَفَةَ .
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."
