Is it permissible not to shave the pubic hair, and suffice with trimming it, in compliance with the husband’s wish, knowing that shaving the pubic hair is part of the Fitra?

It is from the Sunnah for both men and women to shave the pubic hair. The period for neglecting shaving should not exceed forty days. The husband should be convinced of the importance of this Sunnah, which is achieved by shaving all the hair, or trimming most of it with a machine, though shaving with a razor is cleaner.
