Beliefs in Qutubs and Abdals

Question:
1) Is it a part of our aqeedah to believe in the existence of qutubs and
abdals?

2) Can they travel from one part of the earth to another part of the earth in
one second?

3) if yes, is it necessary to believe this unique phenomenon of travelling
from one place to another in one seconds is given to all of the qutubs and
abdals?

4) If someone does not believe that qutubs and abdals exist, will that
individual lose their eeman?

Jazakallah
