“This is about the case of a man to whom one man sends thirty dirham in a piece of cloth, another man sends him twenty dirham in a piece of cloth and they become mixed so much that he cannot distinguish. Abu ‘Abd Allah (a.s.), has said, ‘He must give three-fifths of the value to the man of thirty dirham and two-fifths of the value to the other one.’ I then said the man with thirty has said to the man with twenty, take whichever you like. He (the Imam) said, ‘He has been fair.’”
