it is mentioned that a jinn brought a letter from
Imam Muhammad Baqir (a.s.) and delivered it to Sudair Sairafi and
brought another letter for Jabir Jofi.
When Sudair came to the Imam and narrated the incident, Imam (a.s.) said:
“We are served by jinns, who are under our control
and whenever we delegate a job to them, they carry it
out.”
Twenty traditional reports are quoted in Behaarul Anwaar, in
the chapter that jinns are in the service of the Holy Imams (a.s.) and
they become visible to them and inquire religious issues from them.
