There are some substances such as the yeast and the gelatin that contain very small amounts of pork, or that are extracted from pork; can we use these substances: the yeast and the gelatin?

Answer

Praise Be to Allah and Peace Be Upon His Messenger.

It is not allowed for a Muslim to use substances such as the yeast and the gelatin which are extracted from pork; there are equivalents which are extracted from plants and other animals which meat is halal, and such equivalents are sufficient.
