Muwatta Malik, Book 23, Hadith 9 (USC-MSA)

Yahya related to me from Malik from Abu'z-Zubayr al-Makki that Jabir ibn Abdullah said, "We sacrificed with the Messenger of Allah, may Allah bless him and grant him peace, in the year of Hudaybiya, a camel between seven people, and a cow between seven people."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَبِي الزُّبَيْرِ الْمَكِّيِّ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّهُ قَالَ نَحَرْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم عَامَ الْحُدَيْبِيَةِ الْبَدَنَةَ عَنْ سَبْعَةٍ وَالْبَقَرَةَ عَنْ سَبْعَةٍ ‏.‏
