Book Number: 022 / Hadith Number: 4858
Jabir b. Abdullah reported: We did not eat the flesh of our sacrificial animals beyond three days in Mina. Then Allah's Messenger (may peace be upon him) permitted us saying: Eat and make it a provision (for journey). I asked 'Ata' whether Jabir had also said: Till we came to Medina. He said: Yes.
