Sahih Bukhari Volume 2, Book 26, Hadith Number 777.

Narated By Ibn Juraij : ‘Ata’ said, “I heard Jabir bin ‘Abdullah saying, ‘We never ate the meat of the Budn for more than three days of Mina. Later, the Prophet gave us permission by saying: ‘Eat and take (meat) with you. So we ate (some) and took (some) with us.’ ” I asked ‘Ata’, “Did Jabir say (that they went on eating the meat) till they reached Medina?” ‘Ata’ replied, “No.”
