(What is the ruling on) cutting the hair in different levels, such that the top is longer than the hair on the sides?
What is apparent is that it resembles Qaza’ because Qaza’ is to shave some of the head and leave other parts. And this is shortening some of the head and leaving other parts. He should either shorten all of it or leave all of it just as in shaving the head. He shaves all of it or leaves all of it.
