Narrated Muharib bin Dithar: Jabir bin `Abdullah said, When Allah's Apostle arrived at Medina, he slaughtered a camel or a cow. Jabir added, The Prophet bought a camel from me for two Uqiyas (of gold) and one or two Dirhams. When he reached Sirar, he ordered that a cow be slaughtered and they ate its meat. When he arrived at Medina, he ordered me to go to the Mosque and offer two rak`at, and weighed (and gave) me the price of the camel.
