Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him).
Some people conduct certain activities while calling to Allah which are dubious according to the Sacred Law. They claim they have permission to do so from their shaykh. How do we deal with this?
Firstly, it should be clear that the Sacred Law is above everyone and no-one has permission to transgress it. Our path is founded upon rejecting everything that contravenes the Sacred Law and upon avoiding differences of opinions and doubtful things. Sometimes the opinions of qualified scholars, however, differ regarding certain issues, and this will affect our methodology. Once we have understood these principles we may need to seek clarification on specific issues, for perhaps there are things in them which we are not aware of.
