If you are asking for the specific people in the video, then I don’t know, but the Taliban movement as a whole is majority Maturidi Deobandi with a minority of Salafi Mujahideen. For the Pious Haqqani family, I am not aware that there are any Salafis in it.
@NeutralUser: Ya akhi, I am not sure if this is a question, but the bond between the Mujahideen of al-Qaeda and the Taliban is very much known. As al-Qaeda and other Mujahideen gave their bayah to the Emirate, and from my knowledge, some brothers see them as one Organisation with a part of this Organisation being in Afghanistan, while another is in the Arabian Peninsula and so on. So in short, they are not mere allies but as close as two groups can be to each other.
Are they maturidis or Salafis?
