Commercial Transactions (Kitab Al-Buyu)
Dawud :: Book 22 : Hadith 3383
Narrated Ibn Abbad:
Amr ibn Dinar said: I heard Ibn Umar say: We did not see any harm in sharecropping till I heard Rafi' ibn Khadij say: The Apostle of Allah (peace_be_upon_him) has forbidden it. So I mentioned it to Tawus. He said: Ibn Abbas told me that the Apostle of Allah (peace_be_upon_him) had not forbidden it, but said: It is better for one of you to lend to his brother than to take a prescribed sum from him.
