Please listen to this discussion about Sheikh Abdul Qadir Al-Jilani and his Tareeqa, who his students were, what the principles of the Tareeqa are and what the Sheikh himself has said about the etiquettes of dhikr.
The first video starts with the names of the four khulafa of the Tareeqa being mentioned, who are all Hanbalis and Sheikh Abdul Qadir Al-Jilani's direct students. It should be noted that since his time the overwhelming majority of Hanbalis have been Qadiris.
In the second video there is a Q&A session about the topic.
I pray that you find the discussion beneficial, and with Allah alone is every success.
