If you are looking for Sharia-compliant investments, you can consider some safe and available options in the market that avoid uncertainty and usury. Here are some ideas:

1. Direct investment in cryptocurrencies:

If you are convinced that cryptocurrencies such as Bitcoin or Ethereum are halal, you can buy these currencies directly and hold them. Make sure to avoid trading with leverage or futures contracts to avoid any legal suspicions.

2. Participate in Sharia-compliant investment funds:

There are investment funds that focus on Sharia-compliant investments, such as Islamic equity funds or real asset funds (such as gold or real estate).

3. Sharia-compliant stocks:

Invest in companies listed on the stock exchange that follow the principles of Islamic law, as they avoid companies that operate in areas such as alcohol, usury, or gambling.

4. Trading on Islamic platforms:

There are trading platforms that provide Islamic accounts that are free of usurious interest or illegal fees.

You can consult an Islamic finance specialist to get an investment that suits your principles.
