Is a sale valid when stating 'I sold you from this heap (sabra) every qafiz for one dirham'?
Chapter on Selling Assets and Fruits

Book of Sales
Primary text
The sale is invalid in this case. The particle 'min' (from) implies partiality, while 'kull' (every) implies enumeration, leading to an unknown quantity of the heap being sold. This results in ambiguity regarding the object of sale.
Supporting text
There is a possibility that the sale is valid, analogous to validity in leasing contracts, such as 'every bucket for one date'.
