You said in a previous post that we should just check the ingredients of milk in western countries. They always say milk and Vitamin D3 which can derived from I think sheep wool or fish. What if the sheep was killed before it was taken from its wool, milk is in many products and is hard to stay away

I'm afraid that we are falling into tanatt u' and digging way too deep in regards to some of these questions we are getting. You're making a hypothetical situation, saying maybe it could be taken from this or that. Allah subhanahu wa ta'ala knows best. There are many things where we say it can maybe be taken from this or it can maybe be taken from that, but we need to know the reality of it in order to know the ruling. Allah subhanahu wa ta'ala knows best. So you can see what the norm is. Despite the fact that I am a little bit surprised by such research, which could be an indication of maybe waswas and so on, we have to be sure and not just follow hearsay. And Allah subhanahu wa ta'ala knows best.
