A Muslim should assess the investment by:

1. **Identifying any elements of gharar (excessive uncertainty) or maysir (speculation)**, which are prohibited in Islam.
2. **Consulting with a knowledgeable Islamic scholar** or financial advisor to evaluate the permissibility of the investment.
3. **Ensuring the business activities are halal** and do not involve haram (forbidden) practices.
4. **Avoiding the investment** if it does not fully comply with Islamic principles.
