Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Can we work with ‘Salafi’ groups?
If these groups truly follow the Salaf (the Pious Predecessors) in the realm of tenets of faith then we are in agreement with them. If, however, they claim to follow the Salaf but in reality go against their methodology then we should avoid mixing with them so that confusion does not arise regarding how we call people to Allah. It may be possible to work with the moderate elements among them on things on which there is scholarly consensus and which benefit society. We may also work with them on projects which are run in the name of all Muslims in the region, not in the name of a specific group.
