Mu'jam Kabir Tabarani 1853 — from Ja'far bin Abi Thawr, who narrates

Uthman bin Abdullah bin Mawhab narrates from Ja'far bin Abi Thawr, who narrates from Sayyiduna Jabir (may Allah be pleased with him) that he said: I was sitting with the Messenger of Allah (peace and blessings be upon him) when he (peace and blessings be upon him) was asked: "Should we perform ablution after eating camel meat?" He said: "Yes, perform ablution after eating camel meat." They said: "Should we pray in the resting places of camels?" He said: "No." They said: "Should we perform ablution after eating goat meat?" He said: "If you wish, perform ablution, and if you wish, do not." They said: "Should we pray in the pens of sheep and goats?" He said: "Yes."
