Musnad Ahmad 938:13

Isma'il narrated to us, 'Abd al-Rahman ibn Ishaq narrated to us, from Abu 'Ubaydah ibn Muhammad ibn 'Ammar, from al-Walid ibn Abi al-Walid, from 'Urwah ibn al-Zubayr, who said: Zayd ibn Thabit said: May Allah forgive Rafi' ibn Khadij. I, by Allah, know the hadith better than him. Two men who had fought came, and the Messenger of Allah (peace be upon him) said: "If this is your affair, then do not rent out the farms." He said: So Rafi' heard his saying: "Do not rent out the farms."
