Sayyiduna Hamzah bin Amr al-Aslami (may Allah be pleased with him) said: "I saw the Messenger of Allah (peace and blessings be upon him) at Arafah while my uncle had me riding behind him, and he (peace and blessings be upon him) was placing one of his fingers on the other. I asked (my uncle): What is the Messenger of Allah (peace and blessings be upon him) saying? He said: He (peace and blessings be upon him) is saying: 'Stone the Jamarat with pebbles as small as chickpeas (or broad beans), of the kind that are flicked with the fingers.'"
Imam al-Tabarani (may Allah have mercy on him) said: "Only Yahya bin Ayyub narrated this hadith from Ibn Harmalah, from Yahya bin Hind, from Hamzah bin Amr; Ibn Wahb is alone in narrating it.
And (other) people narrated it from Ibn Harmalah, from Yahya bin Hind, from Asma' bin Kharijah."
