Muwatta Malik 1357
Business Transactions
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، أَنَّهُ سَمِعَ سَعِيدَ بْنَ الْمُسَيَّبِ، يَقُولُ مِنْ مَيْسِرِ أَهْلِ الْجَاهِلِيَّةِ بَيْعُ الْحَيَوَانِ بِاللَّحْمِ بِالشَّاةِ وَالشَّاتَيْنِ .
Yahya related to me from Malik from Da'ud ibn al-Husayn that he heard Said ibn alMusayyab say, "Part of the gambling of the people of Jahiliya was bartering live animals for slaughtered meat, for instance one live sheep for two slaughtered sheep."
