Musnad Ahmad 33:878

'Abdullah ibn al-Walid—meaning al-'Adani—narrated to us, Sufyan narrated to us, from al-A'mash, from Abu Sufyan, from Jabir, who said: A man said to the Prophet, peace and blessings of Allah be upon him: "Which Islam is best?" He said: "That the Muslims are safe from your tongue and your hand." And Waki' narrated it to us, from al-A'mash.
