Undergoing trials

Q: My baby has been having seizures since birth. He has brain damage and other complications. Doctors are perplexed by his problems. His brain mri shows damage but not that much. Still his seizures are persisting despite taking 4 medications twice a day. Medical science is not able to say with certitude what is making him having these seizures (infantile spasms). My baby is 16 months, doesn’t move, doesn’t talk, doesn’t swallow properly, no neck control. I am so so down. I cry with Allah everyday for my child.

Uneven haircut

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?
