Chicken broth can either be extracted from an animal, or it can be made from other materials that give it the flavor of chicken.
If it is the latter, then it is permissible to use it based on the principle of permissibility of the material from which it is made. If it is the former, i.e., extracted from an animal, it can be classified into two cases:
The first: the permissibility of this animal and its prohibition.
The second: the transformation of the extracted substance and its absence.
If the animal is permissible to consume and slaughter according to Islamic law, then it is permissible to use what is extracted from it.
If the animal is prohibited, such as its meat being inherently prohibited, like pork or dogs, or it is not prohibited but was not slaughtered according to Islamic law, then we consider what is extracted from it. If what is extracted is still as it was, it is impermissible to use it. However, if what is extracted has transformed and changed, it becomes purified by the transformation according to the opinion of the majority of scholars, as we have previously mentioned in previous fatwas.
In general, chicken is permissible to consume and can be eaten after being slaughtered according to Islamic law. If the product is from an Islamic country, the default is to assume it is permissible without questioning its origin. If the product is from a country where Jews or Christians are the majority, it is permissible as well based on the permissibility of consuming their food, and the ruling is based on the majority.
If the product is from other countries such as China or India where the majority do not follow the three Abrahamic religions, the ruling depends on whether or not the substance has undergone a transformation or change, as previously mentioned. And Allah knows best.
