Is it permissible to work in companies that deal with usury, or compel employees to [participate in] usurious insurance, and implement a policy of equality between men and women, such as oil and gas companies? And is it permissible to establish a shipping company upon which commercial insurance laws are imposed regarding ships, employees, and products? And is there a list of Sharia-compliant companies?

Firstly: It is permissible for a Muslim to work in companies whose primary activity is permissible, such as oil and gas companies, even if they engage in usury or other prohibited dealings, provided that he does not directly engage in or assist in the prohibited work himself, and that his work is in the permissible departments.

Secondly: Dealing with credit cards that impose usurious interest is prohibited. However, if the company obliges the employee to obtain one, there is no sin on him, provided he does not use it unless he is certain of his ability to pay before the due date for the interest. The same applies to commercial insurance: if the company obliges the employee to take it out due to necessity, there is no sin on him, but he should not benefit from the insurance beyond the amount of premiums he has paid, unless the company is the one that covered it for the employee, in which case the employee may fully benefit from it.

Thirdly: It is permissible to establish a shipping company. If it is compelled to take out commercial insurance, there is no sin in accepting it, but one may not benefit from the insurance company beyond the amount of premiums paid.

Fourthly: Some specialists in Islamic financial transactions issue lists of companies that comply with Islamic Sharia.
