Musannaf Ibn Abi Shayba 8:1832

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Yunus bin Abi Ishaq, from his father, from Sa’d bin ‘Iyad, who said: Ibn Mas’ud was asked about a group of people in the state of Ihram who met a group of people not in the state of Ihram who had with them the meat of game. They either sold it to them or fed it to them. He said: "There is no harm in it."
