What is ghusl required and when is it mustahabb?

Ghusl may be waajib
(obligatory) or it may be sunnah and mustahabb. The scholars (may Allaah
have mercy on them) have described all cases, and their comments may be
divided into three categories: 

1 – Cases in which ghusl is
required according to consensus: 

(i)               
Emission of maniy (semen) even
if it is not through intercourse. 

It says in al-Mawsoo’ah
al-Fiqhiyyah (31/195): 

The fuqaha’ are unanimously
agreed that emission of maniy (semen) is one of the things that make ghusl
obligatory. Al-Nawawi narrated that there was consensus on this point. No
distinction is made between men and women, or whether one is asleep or
awake. The basic principle concerning that is the hadeeth of Abu Sa’eed
al-Khudri (may Allaah be pleased with him) according to which the Prophet
(peace and blessings of Allaah be upon him) said: “Water is for water
(i.e., ghusl must be done when semen is emitted).” Narrated by Muslim (343).
What this means, as was stated by al-Nawawi, is that it becomes obligatory
to do ghusl with water if gushing water is emitted, i.e., maniy. End quote.

(ii)             
Meeting of the two circumcised
parts when the tip of the penis disappears completely in the vagina, even if
no ejaculation takes place.

7529 and
36865. 

(iii)           
and (iv) Menstruation and
nifaas (post partum bleeding) 

In al-Mawsoo’ah
al-Fiqhiyyah (31/204) it says:  

The fuqaha’ are unanimously
agreed that menstruation and nifaas are among the things that make ghusl
obligatory. Ibn al-Mundhir, Ibn Jareer, al-Tabari and others narrated that
there was consensus on this point. The evidence that ghusl is required
following menses is the verse in which Allaah says (interpretation of the
meaning): 

“They ask you concerning
menstruation. Say: that is an Adha (a harmful thing for a husband to have a
sexual intercourse with his wife while she is having her menses), therefore,
keep away from women during menses and go not unto them till they are
purified (from menses and have taken a bath). And when they have purified
themselves, then go in unto them as Allaah has ordained for you”

[al-Baqarah 2:222].

2 – Cases in which ghusl is
not required according to consensus, but it is mustahabb 

(i)               
Every time one is going to meet
people – it is mustahabb to do ghusl beforehand. 

Al-Baghawi (may Allaah have
mercy on him) said: It is mustahabb for the one who wants to meet with
people to do ghusl, clean himself and perfume himself. That includes doing
ghusl on the two Eids. Al-Nawawi (may Allaah have mercy on him) said in
al-Majmoo’ (2/233): It is Sunnah for everyone according to consensus,
men, women and children, because it is part of adoring oneself. End quote.

48988. 

That also includes doing
ghusl before the eclipse prayer, prayers for rain (istisqa’), standing in
‘Arafah, doing ghusl in al-Mash’ar al-Haraam, before stoning the Jamaraat on
the days of tashreeq, and other places where people gather to do acts of
worship or gather according to their customs. 

(ii)             
When undergoing any physical
change. 

Al-Muhaamili – who was a
Shaafa’i faqeeh – said: It is mustahabb to do ghusl every time one undergoes
a physical change.  

For example, the fuqaha’
stated that it is mustahabb for the one who went insane or fell unconscious
to do ghusl when he recovers, and to do ghusl after cupping, after entering
the hammam and so on, because the ghusl will remove anything that has gotten
onto the body and will restore it to a natural state. See al-Majmoo’
(2/235, 234). 

(iii)           
For some acts of worship, such
as doing ghusl when entering ihraam.  

The Prophet (peace and
blessings of Allaah be upon him) did ghusl before changing into his ihraam
garments.  Narrated by al-Tirmidhi, 830. The fuqaha’ stated that it is
mustahabb to do ghusl for tawaaf al-ziyaarah and tawaaf al-wadaa’ (farewell
tawaaf), and on Laylat al-Qadar. When Ibn ‘Umar entered Makkah he would do
ghusl, and he said that the Prophet (peace and blessings of Allaah be
upon him) used to do that. Narrated by al-Bukhaari (1478) and Muslim
(1259). 

3 – Ghusl concerning which
the scholars differed, and which view is more likely to be correct 

(i)               
Ghusl for the deceased. 

The majority of scholars
are of the view that death is one of the things that make ghusl obligatory,
because the Prophet (peace and blessings of Allaah be upon him) said to
the women when his daughter died: “Wash her three times or five or more than
that.” Narrated by al-Bukhaari (1253) and Muslim (939). 

(ii)             
Ghusl after washing the
deceased. 

The scholars differed
concerning this, based on their differences about the hadeeth that was
narrated concerning it. It was narrated from Abu Hurayrah (may Allaah be
pleased with him) that the Prophet (peace and blessings of Allaah be
upon him) said: “Whoever has washed a dead person, let him do ghusl.” 

Narrated by Ahmad (2/454),
Abu Dawood (3161) and al-Tirmidhi (993), who said it is a hasan hadeeth.
Imam Ahmad said in Masaa’il Ahmad by Abu Dawood (309): No hadeeth is
proven concerning this.  

Shaykh Ibn ‘Uthaymeen (may
Allaah have mercy on him) said in al-Sharh al-Mumti’ (1/411): The
correct view is that it is mustahabb. End quote.

6962. 

(iii)           
Ghusl on Fridays 

Al-Nawawi said in
al-Majmoo’ (2/232): It is Sunnah according to the majority, and some of
the salaf regarded it as obligatory. End quote. 

The correct view is that
which was favoured by Shaykh al-Islam Ibn Taymiyah in al-Fataawa al-Kubra
(5/307): It is obligatory to do ghusl on Fridays for one who is sweaty or
has an odour that may offend others. End quote. 

(iv)           
When a kaafir becomes Muslim 

The Maalikis and Hanbalis
are of the view that if a kaafir becomes Muslim, ghusl is required, because
of the report narrated by Abu Hurayrah (may Allaah be pleased with him) that
Thumaamah ibn Athaal (may Allaah be pleased with him) became Muslim, and the
Prophet (peace and blessings of Allaah be upon him) said: “Take him to
the garden of Banu So and so and tell him to do ghusl.” And it was narrated
that when Qays ibn ‘Aasim became Muslim, the Prophet (peace and
blessings of Allaah be upon him) told him to do ghusl with water and lotus
leaves. And in most cases the new Muslim will not be free of janaabah, so
ghusl is required for that reason.  

The Hanafis and Shaafa’is
are of the view that it is mustahabb for a kaafir to do ghusl when he
becomes Muslim even if he is not junub, because many people became Muslim
and the Prophet (peace and blessings of Allaah be upon him) did not
tell them to do ghusl. If a kaafir becomes Muslim when he is junub, then he
has to do ghusl. Al-Nawawi (may Allaah have mercy on him) said: This was
stated by al-Shaafa’i, and the majority of our companions are agreed on
that. End quote. 

Shaykh Ibn ‘Uthaymeen (may
Allaah have mercy on him) said in al-Sharh al-Mumti’ (1/379): In
order to be on the safe side he should do ghusl. End quote. 

And Allaah knows best.
