Sayyiduna Abu Ubayd (may Allah be pleased with him) narrates that he prepared a cooking pot for the Prophet (peace and blessings be upon him) in which meat had been cooked. The Prophet (peace and blessings be upon him) said: "Hand me a foreleg!" I handed it to him. He said: "Hand me its foreleg." I handed it to him. He said: "Hand me its foreleg." He said: "O Prophet of Allah! How many forelegs does a goat have?" The Prophet (peace and blessings be upon him) said: "By the One in whose Hand is my soul, if you had remained silent, you would have kept giving a foreleg for as long as I kept asking for it."
Ahmad and al-Tabarani recorded it, and the narrators of both are the narrators of the Sahih, except for Shahr bin Hawshab, and more than one scholar has declared him thiqah (trustworthy).
