The allegation which the non Ahmadi Muslims raise against Ahmad(as), is that Isa(as) practiced mesmerism and was an expert in it as well, and relate this to Ahmad(as) disrespecting Isa(as), God Forbid. When we read the statement of Ahmad(as) in context, there is nothing objectionable. He(as) stated:
“It must also be understood that healing ailments and transferring the heat of one’s body into another are all parts of the art of mesmerism. Men of this type have always existed who would cure leprosy and other ailments. All those who are highly educated and are well read will agree with me and support my statement that some Naqshbandi and Suharwardi saints also practiced and performed similar services to mankind. Some of them were so well advanced in this field that they would make a very large number of deseased persons sit around them and cast them a glance which would heal them. The well known saint Muhiyud Din Ibne Arabi was much reputed in this art” (Izala Auham, Page 307-308, Ruhani Khazain Volume 3, page 287)
There is no harm in this statement, as Ahmad(as) stated Isa(as) practiced this appropriately during the times which he lived.
