Assalaamu alaykum. If a Muslim butcher store does not sell halal meat anymore, is it still allowed to buy things like herbs from this store, or should you stay away from this store altogether? Could you also share the proof, Allah willing? May Allah reward you.

All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.

It is not forbidden to buy natural herbs and the like from this store, even if it sells what is not halaal (lawful). However, it is preferable to buy from stores that do not sell what is forbidden if it is possible to do so.

Allah knows best.
