Is it permissible for a woman to remove pubic hair during her deceased husband's 'iddah (waiting period)?

A woman whose husband has passed away is permitted to shave her pubic hair during her iddah (waiting period), because this is an act of fitra (natural disposition) and is not considered adornment. It has been narrated in the Hadith: "The fitra are five: circumcision, shaving pubic hair, trimming the mustache, clipping the nails, and plucking armpit hair." Ibn Qudamah also mentioned the permissibility of cleaning oneself by clipping nails, plucking armpit hair, and shaving hair, which are recommended practices.
