A:
The foods that contain prohibited substances such as parts of dead animals and prohibited meats of animals are unlawful to eat. (Part No. 22; Page No. 302) Allah (Exalted be He) says:
Forbidden to you (for food) are: Al-Maitah (the dead animals - cattle - beast not slaughtered)
This rule is applied if all the meat or a part of it is from the dead animals.
