Musnad Ahmad 28:235

'Abd al-Razzaq narrated to us, Muhammad—meaning Ibn Rashid—narrated to us, from Sulayman ibn Musa, from 'Amr ibn Shu'ayb, from his father, from 'Abdullah ibn 'Amr, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "For every finger, there are ten camels, and for every tooth, there are five camels. The fingers are equal, and the teeth are equal." Muhammad said: And I heard Makhul saying—and he did not attribute it to the Prophet (peace and blessings of Allah be upon him). ['Abdullah ibn Ahmad said]: My father said: 'Abd al-Razzaq said: "I have not seen anyone more scrupulous in hadith than Muhammad ibn Rashid."
