Consider the Sukuk as an investment that requires a mini Due Diligence check: Who is the issuer?
Steps
What is the Sharia-compliant structure?
What is the asset or activity?
What is the source of cash flows?
What is the Sukuk's term?
What is the currency?
What are the distributions?
What is the credit rating, if any?
What are the guarantees?
And what is the liquidity for selling before maturity?
If you cannot answer these questions from the prospectus, you still do not have enough information to buy.
