مُوَطَّأُ مَالِكٍ
Muwatta Malik 855
Hajj
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ لاَ يَشُقُّ جِلاَلَ بُدْنِهِ وَلاَ يُجَلِّلُهَا حَتَّى يَغْدُوَ مِنْ مِنًى إِلَى عَرَفَةَ .
Yahya related to me from Malik from Nafi that Abdullah ibn Umar never used to tear the drapes of his sacrificial animals, and he would not drape them until he went from Mina to Arafa.
