سنن أبي داود

Narrated Sulaiman b. 'Amr b. al-Ahwas: On the authority of his mother: I saw the Messenger of Allah (ﷺ) throwing pebbles at the jamrah from the botton of wadi (valley) while he was riding (on a camel). He was uttering the takbir (Allah is most great) with each pebble. A man behind him was shading him. I asked about the man. They (the people) said: He is al-Fadl b. al-'Abbas. The people crowded. The Prophet (ﷺ) said: 'O people, do not kill each other ; when you throw pebbled at the jamrah, throw small pebbles.
