Q: As we know, one cannot shave the one part of the head and leave another because that is qaza which isn’t allowed (and since trimming and shaving aren’t the same thing because we know on the occasion of umrah Rasulullah (sallallahu alaihi wasallam) made a special dua for those who shave their hair and for those who trim it meaning there is a clear distinction).

My question is, what if you trim the sides and not shave, therefore it is not qaza? So if I trim it to about 3+ inches which isn’t short enough to copy or fall under qaza, and I cut with a scissor on top, is this permissible?
