Mishkat al-Masabih #3860

‘Amr b. Shu'aib, on his father’s authority, said his grandfather told that, the Prophet approached a camel, and taking a hair from its hump said, “O people, I get nothing of this booty, not even this (meanwhile raising his finger), but the fifth, and the fifth is returned to you, so hand over threads and needles." A man got up with a ball of hair in his hand and said, “I took this to repair the cloth under a pack-saddle." The Prophet replied, “You can have what belongs to me and to the B. ‘Abd al-Muttalib," but the man said, "If it produces the result I now realise,* I have no desire for it," and he threw it away. *Literally "If it reaches what I see." Abu Dawud transmitted it.
