ويجوز بيع اللحمان المختلفة بعضها ببعض متفاضلا
Translation: Meats of different animal kinds may be exchanged in unequal quantities.
Luhum mukhtalifah are meats from different animal genera, such as goat meat and beef. Quduri permits unequal quantities between these distinct meats. The general word “meat” does not make every animal source a single juristic genus.
Where both are weighed commodities, the shared measure can still bar deferment even though different genera permit unequal quantities. Hence the allowance for unequal amounts must not be mistaken for permission to ignore all other exchange conditions.
