Muslim or Hindu monk, regarded as a holy man (5)
I believe the answer is:
fakir
I believe this is a double definition.
'muslim' is the first definition.
(I know that Fakir is a type of muslim)
'hindu monk regarded as a holy man' is the second definition.
(I've seen this in another clue)
(Other definitions for fakir that I've seen before include "Ascetic type" , "Religious mendicant in India" , "Muslim mendicant monk and holy man" , "Religious ascetic living solely on alms" , "Holy man of the East" .)
