It was narrated from Ayyub
"Ya'la bin Al-Hakim wrote to me (saying): 'I heard Sulaiman bin Yasar narrating from Rafi' bin Khadij, who said: "We used to lease land on the basis of Al-Muhaqalah, leasing it in return for one-third or one-quarter of the yield, and a specified amount of food (produce)."'"
