Narrated Abu Huraira:
The Ansar said (to the Prophet ), "Please divide the date-palm trees between us and them (i.e. emigrants)." The Prophet said, "No." The Ansar said, "Let them (i.e. the emigrants) do the labor for us in the gardens and share the date-fruits with us." The emigrants said, "We accepted this."
