Destroying a place of evil without anyone knowing

We put this question to our shaykh, Shaykh Abd al-Rahmaan
al-Barraak, who answered as follows:

Allaah says (interpretation of the meaning): Let there arise out
of you a group inviting to all that is good, enjoining al-Maruf (Islamic monotheism
and all that Islam orders one to do), and forbidding al-munkar (polytheism and all that
Islam has forbidden) [Aal Imraan 3:104].

The Prophet
(peace and blessings of Allaah be upon him) said:
Whoever of you sees an evil action, let him change it with his hand [by taking
action against it], and if he cannot, then with his tongue [by speaking out against it],
and if he cannot, then with his heart [by feeling that it is wrong], and this is the
weakest of faith.

(Reported by Muslim, no. 70).

Allaah says (interpretation of the meaning): So
keep your duty to Allaah and fear Him as much as you can [al-Taghaabun 64:16].

With regard to the evil thing that you mention in the question, you should
try to change it or get rid of it as much as you can, so that you eliminate it or at least
reduce it. This can be done by taking the matter to the people in authority who have the
power to eliminate it or move it to another area, or by talking to the owner of the site
and asking him to stop investing in evil which will only cause harm to him in this world
and the next, and to invest in something that will be of benefit to him and the people
living in the neighbourhood, without causing them any harm in either their spiritual or
worldly affairs.

As for taking action by destroying the nightclub, as mentioned in the
question, this is not permitted, even if the one who does this is sure he will not get
caught. The evil resulting from such an action is too great, such as the destruction of
property which is it not permissible to destroy, and the accusation and torture of
innocent people that is bound to happen during the investigation of the incident.
Moreover, the owners of the nightclub may not give up, and are most likely to try again to
build the place. Beware, my zealous brother, of being too hasty to change evil things
without thinking about the consequences. It is a good job that you asked this question so
that matters might become clear to you, which they surely are now. And Allaah is the Guide
to the Straight Path.
