How do I find if following are halal?

Salam O Alaikum,

I am trying to figure out if the following are halal. Zoya does not have them. Can someone please guide?

  • Fidelity┬« Water Sustainability Fund ([FLOWX]
  • Invesco Global Infrastructure Fund ([GIZAX]
  • JHancock Infrastructure Fund ([JEEBX]
  • Global X US Infrastructure Development ETF ([PAVE]
  • FlexShares Stoxx Global Broad Infrastructure Index Fund ([NFRA]
  • iShares Global Infrastructure ETF ([IGF]

Zoya currently does not classify mutual funds and ETFs as Halal or not. One option is manually check the holdings of the fund , one by one.

Jazak Allaahu kharun for the advice!
