Shariah compliant investments for trusts

Does anyone on the forum have experience of investing funds as a trustee where the letter of wishes asks that the trustee chooses Shariah-compliant investments?

The fund in question is below the level where a financial advisor will assist, so I am looking at direct investment options.

I would speak to someone at Wahed Invest. Wahed - Halal investing made simple They should be able to point in the right direction. I have a direct contact that I am happy to share if you DM me.
