Assalam o alikum @mannysanny
Welcome to the community.
The first link does not work for me but I suspect that would be the USD version of the same fund. Considering you are a UK investor, its best to buy the GBP version as AJ bell will charge you ~1%FX charge if you buy the USD fund and pay in pounds.
Before you actually do decide to invest in an active fund (typically have very high fees), I would recommend two videos to see what history has shown on Active Vs Passive fund.
- Best Strategy For Stock Market
- Active vs Passive Performance: S&P’s Andrew Innes On His Index vs Active Report
If Tech concentration is a concern, an alternative is MSCI World Islamic Index - a thread elaborating the two funds can be found: Selecting an ETF - #4 by Zeeshan
