The Messenger of Allah (PBUH) bought a camel from me for two uqiyahs and one or two dirhams. He said, when he arrived to Sirar -a village near Medina, he ordered that a cow be slaughtered and they ate from it. When he returned to Medina, he ordered me to go to the mosque and pray two rak’ahs, then he weighed for me the price of the camel and exceeded.
