Ja'far al-Suwa'i narrates from his grandfather, Sayyiduna Jabir bin Samurah (may Allah be pleased with him): "We used to pray in the pens of sheep and goats and did not pray in the resting places of camels, and we used to perform ablution after eating camel meat and did not perform ablution after eating goat meat."
