Muwatta Malik, Book 20, Hadith 143 (USC-MSA)

Yahya related to me from Malik from Abu Jafar al-Qari that Abdullah ibn Ayyash ibn Abi Rabia al-Makhzumi sacrificed two camels, one of them a Bactrian.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي جَعْفَرٍ الْقَارِئِ، ‏.‏ أَنَّ عَبْدَ اللَّهِ بْنَ عَيَّاشِ بْنِ أَبِي رَبِيعَةَ الْمَخْزُومِيَّ، أَهْدَى بَدَنَتَيْنِ إِحْدَاهُمَا بُخْتِيَّةٌ ‏.‏
