I am of Moroccan origin and I live in France. Yesterday a man who is a drinker of alcohol entered the mosque. He is also of Moroccan origin, and this person has done this more than once. Some of the brothers tried to advise him to stop drinking alcohol, but every time he listens to them then he goes back to that and he does not care. Yesterday some of the people lost patience and tried to kick him out, but there are others who say: Let him come in; perhaps Allah will guide him.

What is the ruling on that? How should we handle this matter? Should we let him come in, or what should we do with him?

Praise
be to Allah.

Allah, may He be exalted, says
(interpretation of the meaning):


“O you who believe! Approach not
AsSalat (the prayer) when you are in a drunken state until you know (the
meaning) of what you utter, nor when you are in a state of Janaba, (i.e. in
a state of sexual impurity and have not yet taken a bath) except when
travelling on the road (without enough water, or just passing through a
mosque), till you wash your whole body. And if you are ill, or on a journey,
or one of you comes after answering the call of nature, or you have been in
contact with women (by sexual relations) and you find no water, perform
Tayammum with clean earth and rub therewith your faces and hands (Tayammum).
Truly, Allah is Ever Oft-Pardoning, Oft-Forgiving”


[an-Nisa’ 4:43]

More than one of the scholars
have quoted this verse as evidence that one who is in a drunken state should
not be allowed to enter the mosque. 

Al-Qurtubi (may Allah have mercy
on him) said: 

The scholars differed as to what
is meant by the word “the prayer” here. Some of them said that it
refers to the act of worship itself – this is the view of Abu Haneefah –
hence He said “until you know (the meaning) of what you utter”.
Others said that what is meant is the places of prayer – this is the view of
ash-Shaafa‘i – because elsewhere Allah says (interpretation of the meaning):
“For had it not been that Allah checks one set of people by means of
another, monasteries, churches, synagogues, and mosques [
salawaat],
wherein the Name of Allah is mentioned much would surely have been pulled
down” [al-Hajj 22:40]
; here the places of prayer (mosques) are called
salawaat (lit. ‘prayers’). This interpretation is also supported by the fact
that Allah says (in an-Nisa’ 4:43): “nor when you are in a state of
Janaba, (i.e. in a state of sexual impurity and have not yet taken a bath)
except when travelling on the road (without enough water, or just passing
through a mosque)
”. This implies that it is permissible for one who is
in a state of janaabah to pass through the mosque but not to pray therein.
Other scholars said that what is meant is both the place and the prayer,
because at that time they would only come to the mosque to pray and they
only prayed in congregation, hence the two were inseparable.

This is supported by the fact
that his entering the mosque does not serve any purpose, because he is not
allowed to pray in a drunken state, according to the verse quoted above.
Moreover, his entering the mosque may result in a number of negative
consequences:

1.    
Usually one who is drunk utters inappropriate words

2.    
One who is drunk often causes annoyance or makes the place
dirty, and he will have a foul smell and may act in an odd manner, and the
mosque should be protected from such things.

3.    
One who is drunk often distracts the people in the mosque from
their worship with his words and actions. 

Allah, may He be exalted, says
(interpretation of the meaning): “In houses (mosques), which Allah has
ordered to be raised (to be cleaned, and to be honoured), in them His Name
is glorified in the mornings and in the afternoons or the evenings” [an-Noor
24:36]
. Allah has ordained that the mosques should be raised, i.e.,
purified of all dirt and foul speech, and words and deeds that are not
appropriate in that place. ‘Ali ibn Abi Talhah narrated that Ibn ‘Abbaas
said, concerning the verse “In houses (mosques), which Allah has ordered
to be raised
”: Allah, may He be glorified, has forbidden idle talk and
foul speech therein. 

Something similar was stated by
‘Ikrimah, Abu Saalih, ad-Dahhaak, Naafi‘ ibn Jubayr, Abu Bakr ibn Sulaymaan
ibn Abi Hathmah, Sufyaan ibn Husayn and other scholars and mufassireen. End
quote.

Shaykh al-Islam Ibn Taymiyah
(may Allah have mercy on him) said: 

The prayer of one who is drunk
and does not know what he is saying is not valid, according to scholarly
consensus. In fact it is not permissible to allow him to enter the mosque,
because of this verse and others, because the prohibition is on approaching
the prayer and approaching the places of prayer. And Allah knows best.

End quote from Majmoo‘ al-Fataawa,
22/6 

The author of Mataalib Ooli
an-Nuha fi Sharh Ghaayat al-Muntaha
(2/256) said: those who are like the
drunkard, such as the insane, should be kept away from it, i.e., the mosque,
so as to protect it. End quote. 

But what we advise you to do is
to be gentle and kind to him when making him leave the mosque, so as to
protect the mosque from idle talk and foul speech and so as to prevent
division and arguments between the Muslims in the mosque, in the hope that
this may soften his heart and he will feel comfortable in the mosque, and
make him feel ashamed of his reprehensible actions when he sobers up and
realizes how kind the people were to him even though he was in such a
terrible state. 

And Allah knows best.
