All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
First of all, know that everything the person will get in this life (livelihood, maintenance, blessing, …) has already been determined and prescribed by Allaah. So, the Muslim should only seek that which is lawful in his transaction and his search for gains. The person's livelihood should all be from lawful sources. Indeed, what is forbidden is a cause of deprivation while Taqwa (piety) is a cause of success and easiness of matters. So, do not hasten to join a company which has doubtful earnings and wait until you get a company that stays away from forbidden dealings.
As for working in studying of value creation for shareholders, its rule follows the rule of working in stocks in general. Some scholars hold the opinion that it is lawful to deal in stocks if the company, the person is working for, does not deal in anything forbidden like Riba (interest and/or usury) transactions, making forbidden things or depositing one's money in Riba banks. No doubt that the above conditions cannot be met in Canada, America and Europe. This is because companies in such countries either take Riba loans from the banks or deposit their money in them. Such companies also deal in Riba, gambling, high risks, …etc. Even if we suppose that you can find a company there that meets the Sharee’ah conditions, it is unlawful for you to use interest rate in any study as this is the same as acknowledging Riba transactions. So, we advise you to have trust in Allaah, seek His Help and do your best to get a lawful job. Stay away from Riba companies as to avoid being a writer or witness of Riba or helping in sin and transgression.
Allaah Knows best.
