If he has a wet dream in the wilderness, how can he do ghusl when his friends are present?.,Dought & clear,-

one who has a wet dream when he is in the wilderness, in fair climatic
conditions, and he does not do ghusl, because he feels embarrassed in
front of his friends? How should he do ghusl in the wilderness? Should
he take off all his clothes, because that is embarrassing and he is
afraid someone might see him?.
Praise be to Allaah.
Firstly:
If a person becomes junub as a result of having a wet dream or
otherwise, then he must do ghusl. If he cannot find water, or he can
find it but he fears that he may be harmed by using it because it is
verycold and he cannot find any means of heating it, then he should do
tayammum and pray. As for failing to do ghusl and pray when one has
become junub, out of embarrassment or shyness, that is not
permissible, and it is a grave wrong action and is one of the causes
of punishment in the grave. That has been discussed previously in the
answer to question no. 65731 .
Secondly:
There is no need to be naked when doing ghusl; rather what is
mustahabb for the one who is doing ghusl is to cover his 'awrah with a
waist-wrapper and the like, even if he is doing ghusl on his own.
An-Nawawi (may Allah have mercy on him) said:In the previous chapter
we stated that it is permissible to uncover the 'awrah in cases of
necessity when one is alone, such as when doing ghusl, when urinating
and when being intimate with one's spouse, and the like. In all these
cases it is permissible to uncoverwhen one is alone. But in the
presence of other people, it is haraam to uncover the 'awrah in
allcases.
The scholars said: Covering oneself with a waist wrapper or the like
when doing ghusl is preferable to uncovering oneself, although
uncovering oneself is permissible foras long as it is necessary,when
doing ghusl and otherwise; but doing that more than is necessary is
haraam according to the more correct opinion.
End quote from Sharh Muslim, 4/32
Ahmad (544) narrated from al-Hasan (may Allahbe pleased with him) that
he mentioned 'Uthmaan (may Allah be pleased with him) and his intense
modesty, andhe said: If he were in a room and the door was closed, he
would not take off his garment in order to pour water over himself;
modesty prevented him from standing up straight.
Based on that, if a person is in the wilderness and wants to do ghusl,
he should cover the lower part of his body with a waist wrapper or
garment, and hide beneath a tree or far away from where people can see
him, or he should do ghusl sitting, so that his 'awrah will not be
visible; the 'awrah of a man is the area betweenthe navel and the
knee.
Thirdly:
If a person does not do ghusl in this case and does tayammum
instead,his tayammum is not valid and he has to repeat the prayers
that he offered before doing ghusl.
And Allah knows best.
