Destroying a place
    of evil without anyone knowing
Question

                They are building a nightclub in my
      community and we have tried to no avail to stop this. This will bring great immorality and
      corruption to our community, both to Muslims and non-Muslims. According to the shari'ah,
      is it allowed to destroy this place if no one is caught and the owner will lose all the
      money he invested in it. Is this an acceptable form of reducing evil as commanded in the
      Quran?
Praise be to Allah.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.
