Musannaf Ibn Abi Shayba 3:5463

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: ‘Imran ibn Za’idah ibn Nashit narrated to us, from Nufay’ Abu Dawud, who said: I went out with Ibn ‘Abbas from the mosque, so I took off my sandals. He heard the sound of a pebble [falling], so Ibn ‘Abbas said: "Return it, or else I will dispute with you on the Day of Resurrection."
