Ghusl (Bath) of Friday and 3 faraz of Ghusl

Allah's Apostle ﷺ said, "Anyone of you attending the Friday (prayers) should take a bath."
(Sahih bukhari Volume 2, Book 13, Number 2: )

The three faraz of Ghusl are:

1. Washing mouth and gargling. You need to make sure you wash every part of your mouth. Gargling is a must. (When we are in fasting , we are suppose to just rinse our mouth ; instead of gargling) ..
2. Wash and clean the inner nose up to the soft part.
3. Flow of water on your whole body. All hairs, root hairs, beard etc are included)

The Prophet ﷺ said, "Whoever takes a bath on Friday, purifies himself as much as he can, then uses his (hair) oil or perfumes himself with the scent of his house, then proceeds (for the Jumua prayer) and does not separate two persons sitting together (in the mosque), then prays as much as (Allah has) written for him and then remains silent while the Imam is delivering the Khutba, his sins in-between the present and the last Friday would be forgiven."
