Question:
When one has a haircut, does it have to be one blade (equal length)?
Answer:
Yes, it is important to have an equal length cut. There is a hadith in
Abu Dawood Shareef – “Shave it all or leave it all”,
and “He, s.a.w. forbade Qaza’ for us”.
Qaza’ means shaving part of the head and leaving some hair.
