Fathwa - Ramadhan - Witr prayer

i have 3 small questions:
1. is the shaving of the hair for a man from directly where the navel
is and below that or just around the actual private parts? and what
about the backside area?
2. i have read in some books such as noorul idah that when fasting
ifwater enters from the backside the fast breaks.how can you stop this
happening when doing istinja and ghusl?
3. if in the state of needing farz ghusl whilst fasting to what extent
must the water go in the mouth and nose so that the ghusl is done but
the fast doesnt break?
please answer asap especially as ramadhan is very close.

Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
1) The area immediately under the navel is not to be shaven. The area
of shaving for a male is i.e. from around the private part, scrotum,
going towards the rectum. (Ahsanul Fataawa Vol.8 Pg.78).
2) Below, is the translated text from Hashiyatut Tahtawi Ala Maraqil
Falah commentary of Nurul Idhah,
"Whilst cleansing oneself, the person should strive to loosen the rear
orifice so that asmuch impurity as possible can be removedfrom the
anus, provided one is not fasting. The person fasting, however,should
not do so to prevent the fast from being invalid. Likewise, the person
fasting should avoid inserting a wet finger because it invalidates the
fast. Aftercleansing oneself the rear orifice should be dried before
standing. This will prevent the rearorifice from gathering water
thereby breaking the fast. It is also recommended so as to protect the
garment from being wetted with used water." (HashiyatutTahtawi Pg.48)
Thus, it is understood from the above that not to exaggerate in
cleansing the rear orificewhilst Istinja, and also Ghusl.
3) Gargling is not necessary in Ghusl, but filling and passing
waterinto the mouth is necessary and the Ghusl will be correct. In the
state of fasting you should not gargle. Also, putting water into your
nose till the cartilage (soft bone) is made wet is necessary, it
should not be exaggerated i.e. wetting beyond the cartilage.
Additionally, toexaggerate in washing both mouth and nose is Sunnah.
However, it will be Makruh if one exaggerate in washing both mouth and
nose in the state of fasting, this is similar to if one taste
something whilst fasting.
