If I understand well, before investing in stocks/ETF, we need to :
1- Check if the stock/ETF is halal
2- Calculate Zakat
3- Calculate the purification amount
First, to check the halalness, some islamic screener or ETF issuer approve that the equity is halal but other disapprove it. Example: Apple, MSFT
Second, the Zoya Zakat calculator is GREAT but I can not find a lot of european and Japanese stocks. And based on Zoya Zakat calculator, I should avoid some sectors like Gas&oil because the zakat amount exceeds 2% of the total invested amount. If I add US withholding tax, french taxeS and inflation, I am sure to loose money.
Third, I didn’t find a purification amount calculator. So if I consider that the non halal part is 5%, I have to donate each year 5% of the net profit and 5% of capital gain when I sell the stock/ETF.
My question is : is there any simpler way to invest halal?
For the moment, the only halal simple investment that I found is MSCI Saudi Arabia ETF because saudi companies pay already zakat and there is no purification amount to pay.
