According to Zulkifli Hasan (tt), the characteristics of properties that do not comply with Sharia are as follows:
- Property that is produced from activities that are clearly contrary to the Sharia;
- Property whose legal status is disputed between halal and haram; and
- Property where there is a mix between halal and haram from the point of view of 'ain (things) or actions.
Examples are income from illegal activities such as the sale of grapes to winemakers, wages for bringing wine from factories to supermarkets that sell alcohol, and the sale of weapons to the enemy of Islam.
In a financial context, an example is interest earned from deposits in conventional bank accounts.
According to Mohd Sabree & Khairul Azhar (2019), the Shariah Advisory Council (MPS) of the Securities Commission (SC) sets the criteria for a company's securities to be classified as non-Shariah-compliant if the company's core activities are not in line with Shariah as follows:
- Financial services based on usury (interest);
- Gambling and betting;
- Production or sale of non-halal goods or related goods;
- Conventional insurance;
- Entertainment activities that are not in line with Sharia;
- Production or sale of tobacco-based goods or related goods;
- Broking or buying and selling of non-Sharia compliant securities; and
- Other activities that were found to be inconsistent with sharia.
