When a Muslim is offered an investment opportunity that involves speculation, they should assess whether the investment is permissible by considering the following steps:

*I. Understanding Islamic Principles*

1. _Prohibition of Riba (Interest)_: Ensure the investment does not involve Riba, which is strictly prohibited in Islam.

2. _Prohibition of Gharar (Uncertainty)_: Verify that the investment does not involve excessive uncertainty or speculation, which is also prohibited.

3. _Prohibition of Maisir (Gambling)_: Confirm that the investment is not akin to gambling, which is forbidden
