Buying and Selling: Selling the Meat of a Female Animal Instead of a Male Animal
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 2149
If a butcher sells the meat of a male animal but gives the meat of a female animal instead, he will have sinned. Therefore, if he specifies the meat and says, ‘I am selling this meat of a male animal’ [but gives the meat of a female animal], the buyer can annul the transaction. However, if he does not specify it, then in case the buyer is not pleased with the meat he has received, the butcher must give him the meat of a male animal.
