Musnad Ahmad 117:2

Hashim narrated to us, Abu Mu'awiyah—meaning Shayban—narrated to us, Yahya—meaning Ibn Abi Kathir—narrated to us, from Abu Salamah, who said: Ya'ish ibn Takhfah ibn Qays informed me, from his father, and his father was one of the people of the Suffah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "O so-and-so, take this with you." And he mentioned its meaning.
