Halaal Food & Drinks

Mice droppings on food

Q: My wife made rotis yesterday and placed them in a container. When they were cool she covered them. We had rotis for supper last night. After esha, when I was in the kitchen, I saw a mouse eating from a wrapped left-over sandwich. Later, I put the roti container in the fridge. After fijar, my wife took out the roti container from the fridge. She saw mice droppings or "stools" on the side of rotis in the container. 

1. What do we do with the rotis? 

2. What do we do if we have a mice problem?

Rennet

Q: Could you please send me the details of the shar'ee ruling on cheese, as most of them contain animal rennet.

Herbal teas

Q: I was wondering, since we as Muslims need to break away totally from all forms of shirk, is it permissible to drink tea from companies that use doasit, or ayurvedic medicine? I am concerned with the companies using medicinal protocols that stem from shirk. Although the teas of herbal formulations would be completely halaal in terms of just being plant made, can we still buy and use them due to them being derived form those kinds of wrong medicial practices?
