Musnad Ahmad 289:21

Bahz and ‘Affan narrated to us, they said: Abu ‘Awanah narrated to us, he said: Ya’la ibn ‘Ata’ narrated to us, from Waki’ ibn Hudus al-‘Uqayli, from his paternal uncle Abu Razin—who is Laqit ibn ‘Amir—he said: Abu Razin informed me that he said: "O Messenger of Allah, we used to slaughter sacrifices in Rajab, so we would eat from them and feed from them whoever came to us." He said: The Messenger of Allah (peace and blessings of Allah be upon him) said to him: "There is no harm in that." He said: Waki’ said: "I will never abandon it."
