Source-dependent Peer-reviewed Shafi'i fiqh analysis: feather- and wool-derived keratin is permissible only where it comes from an edible (halal) animal and the processing involves no haram substances. Shafi'i jurists hold the feathers and fur of an edible animal pure whether taken before or after death, while the hair or fur of a non-edible animal follows that animal's own impure ruling. Species and processing chain therefore decide the outcome.
