Sahih Muslim | Book 21 | Hadith Number 4807

Narrated by 'Abdullah b. Mughaffal
'Abdullah b. Mughaffal reported that Allah's Messenger (may peace be upon him) prohibited throwing of pebbles. Ibn Ja'far reported (in the narration transmitted by him) that he (the Holy Prophet) said: It neither inflicts defeat to the enemy nor kills the game but breaks the tooth and puts the eye out. This hadith has been transmitted on the authority of Ibn Mahdi with a slight variation of wording.
