Sunan An-Nasa'i

It was narrated from Ibn Khabbab - who is 'Abdullah bin Khabbab - that:Abu Sa 'eed Al- Kahudri arrived from a jouney and his family offered him some meat from the sacrificial animal. He said: ""I am not going to eat it until I ask about it,"" So he went to his half-brother through his mother, Qatadah bin An- Nu man who had been presently at Badr, and asked him about that. He said: ""The opposite of what you were forbidden occurred after that, and (Permission was granted) to eat the sacrificial meat after three days"" (Sahih)
