Ruling on renting out a hall to someone who will hold a mixed party there

Question

Praise be to Allah.

It is not permissible to
rent out halls to those who will hold parties that involve sinful things,
such as mixing between men and women, or haraam music and other sins,
because Allaah says (interpretation of the meaning):

“Help you one another in
Al‑Birr and At‑Taqwa (virtue, righteousness and piety); but do not help one
another in sin and transgression. And fear Allaah. Verily, Allaah is Severe
in punishment”

[al-Maa’idah 5:2]

The scholars (may Allaah
have mercy on them) stated that it is haraam to rent out a house to one who
is going to use it in disobedience of Allaah.

It says in Mataalib Ooli
al-Nuha (3/607): It is not valid to rent out a house to be used as a
church, synagogue, monastic cell, house of fire for Magian worship, for
selling alcohol or gambling, because that is helping in sin and Allaah says
“do not help one another in sin and transgression”. (And it is not
valid) to rent the house out for music or anything else that the Lawgiver
has forbidden. End quote.

It says in al-Mawsoo’ah
al-Fiqhiyyah (8/228): Because the purpose of the rental contract is to
sell use of the house for a specific period, the same stipulation is made
concerning its use as is made in a contract of sale, which is that there
should be no shar’i impediment to the use made of it such as it being
haraam, as in the case of alcohol, musical instruments and pork. According
to the majority of fuqaha’ it is not permissible to rent out a house for
purposes that are not acceptable according to sharee’ah, such as if the
renter is going to use it as a place for drinking alcohol or gambling, or he
is going to use it as a church or place of idol-worship. In that case it is
haraam to take the rent just as it is haraam to give it, because that is
helping in sin. End quote.

And Allaah knows best.
