How can I navigate the ethical dilemma surrounding my fiance's elder brother, who works in an Islamic bank which is considered haram, potentially making his earnings questionable? As my fiance and I are planning to have a separate household after marriage, how do I reconcile accepting gifts or food from his elder brother while being aware of the source of his earnings? This situation is causing me to question our union despite my fiance being a wonderful person. Additionally, the close bond between the brothers and their frequent interactions further complicates my feelings about this matter. How can I address this concern while respecting the relationships and dynamics involved?
