Abdullah bin 'Amr said:"I heard the Messenger of Allah say: 'Perform ablution after (eating) camel meat, but do not perform ablution after (eating) mutton. Perform ablution after (drinking) camel's milk, but do not perform ablution after (drinking) sheep's milk. Perform prayer in the sheep pens but not do in the camels' Ma'atin
