Musannaf Ibn Abi Shayba 27:655

Abu Mu'awiyah narrated to us, from al-Shaybani, from Muhammad ibn Ubayd Allah al-Thaqafi, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Mu'adh will be before the scholars on the Day of Resurrection by a distance of a stone's throw."
