It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When a person eats from a voluntary hady (a sacrificial animal sent to the Haram), he becomes liable (that is, he has to pay compensation for it)."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) except with this chain, and Khalid (bin Abdullah, may Allah have mercy on him) is alone in narrating it."
