1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr ibn ‘ Atiyyah who has said the following: “This is concerning my question before abu ‘ Abd Allah , about the case of our buying food from ships. We then measure and find extra amount. He (the Imam) said, ‘Perhaps you find it to be less also.’ I replied, ‘Yes, that also happens.’ He (the Imam) then asked, ‘Do they give you the deficit?’ I replied, ‘No, they do not give the deficit. He (the Imam) said, ‘It is not harmful.’”
