The concept of Jallalah demonstrates the high standards of animal welfare and public health in Sharia law. If a chicken or cow is found eating impurities, its biological state is considered compromised. Scholars established specific "purification periods",such as 40 days for camels and 3 days for chickens,during which the animal must be fed only pure feed. Once the traces of filth are gone and the animal is healthy, it becomes Halal for consumption. This highlights that "Halal" is not just about the method of slaughter, but also the entire lifecycle and cleanliness of the food source. Jallalah refers to livestock or animals that have consumed filth, waste, or impure substances (Najis) to the extent that it changes the smell or taste of their meat or milk. In Islamic jurisprudence, consuming the meat of a Jallalah animal is considered "Makruh" (disliked) or "Haram" (forbidden) until the animal has been quarantined and fed clean food for a specific period of time (Istibra). This ruling reflects Islam's commitment to "Halalan Tayyiban" (permissible and pure), prioritizing food safety, hygiene, and the physical well-being of the believers. The prohibition of jallalah meat is based on the Prophet's guidance. He prohibited eating the meat of animals that eat filth. The period of istibra (purification) varies: for camels, it is 40 days; for cows, 20-30 days; for sheep and goats, 10-20 days; for chickens, 3-5 days. During this period, the animal is fed clean food, and its meat becomes pure. The ruling on jallalah is a precaution. If the impurity is minimal and does not affect the meat's taste or smell, some scholars consider it permissible. However, the general principle is to avoid what is questionable. Jallalah also applies to milk. If an animal consumes filth, its milk is also considered impure until the animal is purified. For believers, the concept of jallalah teaches that halal is not just about slaughter but about the entire life of the animal. Muslims should be mindful of what animals eat, ensuring they are raised with pure feed. They should also be mindful of their own bodies, consuming only what is pure and wholesome. The ultimate goal is to consume what is tayyib (pure, wholesome), as Allah commands: "O you who have believed, eat from the good (tayyib) things which We have provided for you" (2:172).
