Abu Razin (may Allah be pleased with him) said: O Messenger of Allah, in the Jahiliyyah we used to slaughter animals, eat from them and also feed those who came to us. He (peace and blessings be upon him) said: "There is no harm in that." Waki' (may Allah have mercy on him) said: I will never abandon it. Others narrated it from Abu Awanah and said: We used to slaughter animals in Rajab.
