Is this ETF worth investing in?

Hello, I need some advice on iShares MSCI USA Islamic UCITS ETF (ISUS) which is trading on the LSE.

As the stock market is volatile atm, I want to DCA into a low cost ETF but it has to be shariah compliant and as I'm from the UK, this ETF is available in my broker.

Are the holdings, performance compared to S&P500/other ETFs and expense ratio worth investing in?

Thanks
