May this question reaches you with the fear of Akhera in your heart and intention to purify a brother.
I work in a international company as a merchant. My job is to sell products (IT) to end user. While doing costing I have to add interest (bank rate or higher) on the product as the investment for the products are done very early in the process and customer pays the bill after user acceptance test ( UAT). My question is, am I doing a halal Job or a haram one. What is the ruling on my condition. Is my income for last few years halal, if not how to purify it. I am a salaried employee. The company which I work for is a service oriented company and 90% of the income that I know of is free of interest.
May Allah lightens your knowledge that you may guide others with that light.
