Shias

Asalamu alaikum respected Mufti sahab.
I want to ask you about the Shia sect.

1)Mufti Rasheed Ahmed Ludhianvi rahmatullah alaih had written that all Shias are Kafir and Zindeeq.He said that even if any of them did not have kufr beliefs,but they still called themselves Shia,then they will be out of the fold of Islam. Do you agree with this?

2)Are Shias zindeeqs or not?

3)Are Qadianis zindeeqs or not?Which is the worse Kafir,Shia or Qadiani?

4) Are the Zaidi Shias of Yemen also Kafir? (they would be according to Mufti Rasheed Ludhianvi’s rule).
