Musnad Abu Ya'la al-Mawsili 159:62

Narrated to us Wahb, with his chain of narration, from Abu Hurayrah, that the Ansar said: "O Messenger of Allah, divide the wealth between us and our brothers from the Muhajirin." He said: "Do you not suffice them the burden (of labor)?" So they divided the fruit. They said: "We hear and we obey."
