Is unshaven pubic hair considered a barrier to ghusl, given that it is difficult to shave completely and takes a long time?

Shaving the pubic hair is recommendable (mustahabb) but not obligatory (wajib), and it is not a condition for the validity of ghusl (ritual bath). It suffices to make the water reach all parts of the body and to run the fingers through the hair so that the water reaches its roots. One must disregard the whisperings of the invalidity of ghusl without shaving the pubic hair.
