Wa ʿAlaykum Al-Salām, As far as I'm aware, every tariqah has some form of muraqabah. Some might be the same or different in terms of what is being visualized (ex. Soharwardiyya vs. Naqshbandiyya) but the concept of muraqabah is there.
As-salamu alaikum, I know Muraqaba is a prominent feature of the Naqshbandi silsila(s). Does Muraqaba play a role in other silsilas as well?
