I have a few questions. What exactly is bayah tabarruk in the Naqshbandi tariqa? What does it entail? Does one have permission to do the dhikr, salawat and awrad of the tariqa if they do bayah tabarruk? And what must one do to continue getting the barakah from the Tariqa? Must one do the daily devotions? If one does bayah tabarruk does one have have a spiritual connection with all the awliya of the Chain?
wa `alaykum salam,
Baya` tabarruk does not require observing the practices of the Tariqah, but is only for obtaining the baraka of the Shaykh. It will give you spiritual support from the Shaykh and his lights will dress you in-sha-Allah, and Allah knows best.
