Re: Savings Accounts/Retirement funds
The counter argument to that is that you are only responsible for your own money and actions. For example, if you run a store selling sweets, you are allowed to sell meat even to a non-Muslim wine merchant, even though they money that he pays you with is money he made in an Islamically forbidden trade.
So it doesn’t matter what your employer does,instead it’s your own actions. (I’ve seen fatwas going one step further and saying that this means that it’s permissible to work in an IT position in a bank running their computers, whereas working as a bonds trader for the same bank would not be allowed). I’ve got a very religious relative who applies to logic to his work as an accountant in a non-halal meat company. He states that since he’s just calculating numbers and making sure the company follows the law, rather than personally actively selling or distributing pork, then there is nothing wrong with his work or income…
