Praise be to Allah.
Removing the pubic hair , whether by plucking, using a depilatory agent, shaving or cutting, is one of the actions dictated by the fitrah and encouraged by Islam, but it is not restricted to or required at the end of every period .
Ahmad, al-Bukhari, Muslim and the authors of Sunan reported that the Messenger of Allah (peace and blessings of Allah be upon him) said: “Five things are part of the fitrah : removing the pubic hairs , circumcision, trimming the moustache , plucking the armpit hairs, and trimming the nails.”
Anas (may Allah be pleased with him) said: “A time limit was set for us with regard to trimming the moustache, cutting the nails, plucking the armpit hairs, and shaving the pubic hair – we should not leave it for more than forty days. (Reported by Muslim, Ibn Majah, Ahmad, al-Tirmidhi, al-Nasai and Abu Dawud). They said: “The Messenger of Allah (peace and blessings of Allah be upon him) set a time limit for us…”
And Allah knows best.
