Yahya related to me from Malik from Da'ud ibn al-Husayn from Abu Sufyan, the mawla of Ibn Abi Ahmad, from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, allowed the produce of an ariya to be bartered for an estimation of what the produce would be when the crop was less than five awsuq or equal to five awsuq. Da'ud wasn't sure whether he said five awsuq or less than five.
