Khirash bin Jubair said: I saw a young man in the mosque who was throwing pebbles. An old man said to him: Do not throw pebbles, I heard the Messenger of Allah (peace be upon him) forbidding the throwing of pebbles. The young man was negligent and thought that the old man was not watching him, so he started throwing pebbles again. The old man said to him: I narrate to you a hadith that I heard the Messenger of Allah (peace be upon him) forbidding the throwing of pebbles, and yet you are doing the same? By Allah, I will neither attend your funeral, nor visit you if you fall ill, nor ever speak to you. I said to my companion, whose name was Muhajir: Go to Khirash and ask him. So he went to him and asked about this, and he narrated this hadith to him as well (i.e., he confirmed it).
