What did the Prophet Muhammad (saw) say when Jabir (peace be upon him) invited him to partake in a meal of ground barley and a young sheep?
 Narrated Jabir bin `Abdullah:                     I said, "O Allah's Apostle! We have slaughtered a young sheep of ours and have ground one Sa of barley. So, I invite you along with some persons." So, the Prophet said in a loud voice, "O the people of the Trench! Jabir had prepared "Sur" so come along."
