Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
A brother wants to help out in a particular institution but there are questionable things related to this institution. Should he take part or not?
Firstly we should take part in serving the Muslim community via the various institutions which are following correct understandings. If, however, the only way to serve the Muslims is via organisations that do questionable things then we should serve in these organisations as long as these questionable things are not severe in the sight of the Sacred Law. However, we should avoid taking part in the specific activities which are questionable and focus on the good that the organisation does in serving Muslims.
