Sulayman bin Amr narrates from his mother (may Allah be pleased with her): I saw the Messenger of Allah (peace and blessings be upon him) riding at the Jamrah, and behind him was a man shielding him from the people's stones. He (peace and blessings be upon him) said: "O people, do not kill one another; whoever stones the Jamrah, let him throw small pebbles." She said: I saw stones between his (peace and blessings be upon him) fingers; he (peace and blessings be upon him) stoned, and the people stoned too, then he (peace and blessings be upon him) turned back.
