I transferred my work pension from a conventional fund to a Sharia compliant fund.
However, this was done by the pension provider as a selling off the old fund and purchase of the halal fund. This purchase would have included the profits made from the conventional fund and so there is a risk that this would have included non halal profits in it.
I am particularly worried about this relatively small amount compounding over time to become more, mixed into the halal profits from the Shariah compliant pension.
Is there a practical way of purifying this? Keeping in mind that I was in the non halal pension for 5 years and have been in the halal pension for 3 years.
The amount I need to give away as purification, does that have to come from the pension fund, or can I just give it away from a different source, i.e. my personal bank account? For example, if £100 in my pension fund is from haram sources, can I donate £100 to charity from my personal bank account, instead of taking the £100 from the pension and giving it to charity?
