"A fellow in the broadest sense is someone who is an equal or a comrade. The term fellow is also used to describe a person, particularly by those in the upper social classes. It is most often used in an academic context: a fellow is often part of an elite group of learned people who work together as peers in the pursuit of knowledge or practice." I don't think the word "fellow" was insulting... and in the academic sense, an alim is indeed a fellow!
