Sayyiduna Abu Hurayrah (may Allah be pleased with him) reports about the Prophet (peace and blessings be upon him) that he forbade the sale of foodstuff until the two sa' (measures, of both parties) have been applied to it, so that any excess goes to its owner and any shortfall is borne by him. (Allamah al-Haythami says:) I say: The hadith of Sayyiduna Abu Hurayrah (may Allah be pleased with him) in the "Sahih" is about the prohibition of selling foodstuff before measuring it.
Al-Bazzar recorded it; its chain contains Muslim bin Abi Muslim al-Jarmi, and I have not found anyone who has written his biography; the rest of its narrators are the narrators of the Sahih.
