All Praise to Allah Swt and blessings on Prophet Muhammad peace be upon him His Family and Companions.
There are 3 Fardh in ghusl,
1.Rinsing the mouth.
2.Sniffing water upto nose.
3.Washing every visible part of the entire body
Now The Sunnah way of Ghusl:
1.Without Pronouncing anything verbally make an intention in your heart
to perform Ghusl (I am performing Ghusl in order to purify myself)
2. First wash both hands upto your wrist 3 times and then wash the
private parts(regardless of whether you could see any impurity).
3.Then
wash any impurity from your body( if any).
4.Perform whole wudhu the
way you would for Salah including rinsing of mouth and sniffing upto
nose ,but do not wash your feet(unless you are standing on something
elevated like a stool).
5.Rub water on your whole body like Oil.Pour
water three time over your right shoulder,then three times over the
left and then same no of times over your head and the rest of the
entire body.
6.Now wash your feet. Do not face the Holy Kaaba while
performing Ghusl and rub your hands all over body whilst washing
(washing means at least 2 drops of water has passed over an area) and
do not talk while doing ghusl,there is no harm in drying oneself with
a towel after finishing.
From Book of Hanafi jurisprudence
Narrated Hisham bin Urwa:
(on the authority of his father)
Aisha said,
"Whenever Allah's Messenger (ﷺ) took the bath of Janaba, he cleaned his hands and performed ablution like that for prayer and then took a bath and rubbed his hair, till he felt that the whole skin of the head had become wet, then he would pour water thrice and wash the rest of the body." `Aisha further said, "I and Allah's Messenger (ﷺ) used to take a bath from a single water container, from which we took water simultaneously."(Bukhari)
Allah Swt and His Messenger knows best.
