Referring to Question 4540 Marriage to a girl whose father is a banker. If I am married then how to deal with it?

In principle, it is not permissible for a person to work in a commercial bank and actively engage in any Haraam transaction. For example, doing an interest bearing deal. The income from such an amployment is not permissible.

If a person is not directly engaged in any Haraam transaction, for example, an accountant at a bank recording the transaction that had taken place, then too he should not work there. However, the income due to his accounting services will not be Haraam. We also wish to point out that apart from the above general principle, one must take into cognizance his relationship with people especially relatives. To maintain family ties is Fardh and to break family ties is Haraam and emphasized injunction of Shari'ah. One must be prudent in abstaining from Haraam in a way that does not lead him to commit another Haraam act.

and Allah Ta'ala Knows Best
