Taking the ritual bath for Friday prayers is a sunnah. In Islam, the term "sunnah" refers to the actions and sayings of the Prophet Muhammad, which serve as an example for Muslims to follow. Although taking a ritual bath (ghusl) is not mandatory for Friday prayers, it is highly recommended as a means of purifying oneself and showing respect for the special day. The Prophet Muhammad himself would take a ritual bath on Fridays before attending the congregational prayers, and so Muslims consider it a sunnah to do the same. While it is not obligatory, it is a virtuous act and is considered to bring one closer to God.
