It is narrated from Hazrat Ibn Mughaffal that once he saw one of his companions throwing pebbles. He said to him, "Do not do this, because the Prophet (peace be upon him) forbade anyone from throwing pebbles and said that neither can an enemy be subdued by it nor can any game be hunted by it. However, it can break a tooth or put out an eye." After some time, he again saw him throwing pebbles and said, "I narrated to you the hadith of the Prophet (peace be upon him), and yet I see you doing the same thing. From today onwards, I will not speak to you in this manner."
