Sayyiduna Jabir bin Samurah (may Allah be pleased with him) said: A man passed by the Messenger of Allah (peace and blessings be upon him) and said: Should I perform ablution after eating the meat of camels? The Prophet (peace and blessings be upon him) said: "Yes." He said: Then may I pray in the resting places of camels? The Prophet (peace and blessings be upon him) said: "No." He said: Then should I perform ablution after eating the meat of sheep? He said: "If you wish, perform ablution, and if you wish, do not." He said: Then may I pray in the pens of sheep? He said: "Yes."
