The Ruling on Eating Chicken Which Has Been Fed on Pork

Question :

The Permanent Committee for Scientific Researches and Religious Verdicts studied the following question from the Muslim brothers in Bani Murad district to His Eminence, the Director General, which was referred to them. with the number 286 on the 10th of Safar 1401 A. H., the text of which was as follows: "They feed chicken with mixed foods. Included among these foods is meal from the meat of dead animals, including pork. Are these chickens which are fed on this meat permissible or forbidden? And if they are forbidden, what is the ruling on their eggs?

Answer:

The Committee answered as follows: If the situation is as described regarding the feeding (of the chickens), there is a difference of opinion among the scholars regarding the eating of its meat and its eggs. Malik and a number of others said that eating its meat and its eggs is permissible, because the impure foods are purified by their transformation into meat and eggs. And a number of them, including Ath-Thawri, Ash-Shafi'i and Ahmad held that it is forbidden to eat it, as well as its eggs, and to drink its milk."

And it was said: If most of its fodder was impure, then it is Jallalah and it may not be eaten. If most of its fodder is pure, it may be eaten. And a number (of scholars) said that it is forbidden, based upon the Hadith narrated by Ahmad, Abu Dawud, An-Nasa'i and At-Tirmithi, on the authority of Ibn 'Abbas, may Allah be pleased with them, in which it is stated that the Messenger of Allah forbade drinking the milk of Al- Jallalah, and it was declared authentic by At-Tirmithi and Ibn Daqiq Al-'Eid. (They also cited as evidence) the narration of Ahmad, Abu Dawud, At-Tirmithi and Ibn Majah, on the authority of Ibn 'Umar, may Allah be pleased with them, which states that the Messenger of Allah forbade eating the meat of Al-Jallalah and drinking its milk. Al-Jallalah is the animal that eats excrement and all other kinds of impure things. And the most authoritative view is the one that elaborates on the details, which is the second, as we have said.

And may peace and blessings be upon our Prophet, Muhammad and upon his family and Companions.
