Ruling on opening mosques with celebrations and gathering for that purpose

Mosques are opened by praying in them and maintaining them
with the remembrance of Allaah (dhikr), reading Qur’aan, glorifying and
praising Allaah, declaring His Oneness, teaching knowledge of sharee’ah, and
other things that will show respect to the place. Allaah says
(interpretation of the meaning): 

“In houses (mosques)
which Allaah has ordered to be raised (to be cleaned, and to be honoured),
in them His Name is remembered [i.e. Adhaan, Iqaamah, Salaah (prayers),
invocations, recitation of the Qur’aan]. Therein glorify Him (Allaah) in the
mornings and in the afternoons or the evenings,

Men whom neither trade nor sale (business) diverts from
the remembrance of Allaah (with heart and tongue) nor from performing
As-Salaah (Iqaamat-as-Salaah) nor from giving the Zakaah. They fear a Day
when hearts and eyes will be overturned (out of the horror of the torment of
the Day of Resurrection).

That Allaah may reward them according to the best of their
deeds, and add even more for them out of His Grace. And Allaah provides
without measure to whom He wills”[al-Noor 24:36-38]

In these ways and others, by offering religious advice,
exhortation and consultation, the Messenger of Allaah (peace and
blessings of Allaah be upon him) used to maintain the mosque, and he was
followed in that by the Rightly-Guided Khaleefahs and by all his Sahaabah
and the guided imams after him (may Allaah be pleased with them and have
mercy on them). All goodness resides in following their guidance and
adhering to their example in opening mosques and maintaining them as they
did, with acts of worship and other symbols of Islam. It was not narrated
that the Prophet (peace and blessings of Allaah be upon him) or any of
the guided imams opened a mosque with celebrations or invitations like those
that people do nowadays, gathering from all over the country when the
building is complete to honour it. If that was a praiseworthy action, then
the Messenger of Allaah (peace and blessings of Allaah be upon him)
would have been the first of people to do it and he would have prescribed it
as Sunnah for his ummah, and the Rightly-Guided Khaleefahs and guided imams
who came after him would have done it too. And if that had happened, it
would have been reported. 

On this basis, these
celebrations should not be held. It is not recommended to invite people to
such events or to help with them by giving money or in other ways. All good
resides in following those who went before (the salaf) and evil resides in
following those who came later. The fact that one of the Sahaabah invited
the Messenger of Allaah (peace and blessings of Allaah be upon him) to
his house to pray two rak’ahs in one part of it so that the owner of the
house could take that as a prayer-place for praying whatever he could of
naafil prayers does not form evidence to support the modern practice of
holding celebrations to open mosques, because he (the Sahabi) did not invite
the Prophet (peace and blessings of Allaah be upon him) to a
celebration, rather he invited him to pray, and he did not travel in order
to offer that prayer. Moreover, travel to attend this celebration or to pray
in that mosque comes under the general meaning of the prohibition on
traveling to pray in mosques other than the three famous mosques [i.e.,
al-Masjid al-Haraam in Makkah, al-Masjid al-Nabawi in Madeenah and Masjid
al-Aqsa in al-Quds/Jerusalem]. So we should shun this innovated practice and
be content – with regard to mosques and other matters – with the things that
were done at the time of the Messenger of Allaah (peace and blessings
of Allaah be upon him) and the guided imams who followed him (may Allaah
have mercy on them).
