Sahih Muslim 360 a
Jabir b. Samura reported:
A man asked the Messenger of Allah (may peace he upon him) whether he should perform ablution after (eating) mutton. He (the Messenger of Allah) said: Perform ablution it you so desire, and if you do not wish, do not perform it. He (again) asked: Should I perform ablution (after eating) camel's flesh? He said: Yes, perform ablution (after eating) camel's flesh. He (again) said: May I say prayer in the sheepfolds? He (the Messenger of Allah) said: Yes. He (the narrator) again said: May I say prayer where camels lie down? He (the Holy Prophet) said: No.
