If someone is uncertain about whether their wealth has been entirely earned through halal (permissible) means in Islam, it’s important for them to take steps to rectify the situation and ensure future earnings are in full compliance with Islamic law. Here’s a detailed guide on how to approach this matter:
1. Self-Reflection and Investigation

• Assess Sources of Income: The first step is to carefully examine the sources of income. Reflect on all the ways through which wealth has been accumulated (e.g., business profits, investments, salary, inheritance). Try to determine whether any portion of the wealth has come from haram (forbidden) sources, such as:
  • Interest (riba) from bank loans or investments.
  • Income from gambling, alcohol, or other prohibited industries.
  • Unlawful business practices, such as fraud, deceit, or exploitation.
• Identify Ambiguities: If you’re uncertain about specific sources (e.g., mixed investments or unclear income streams), try to clarify these sources by reviewing contracts, transactions, and business dealings.
