Taxi driver taking
    passengers to forbidden places
Question

                Assalaamu 'AlaykumA brother is a taxi driver and faces some difficulties for which he
      requires sincere advice.He says that often times a passenger will get in the vehicle and after a
      portion of the journey asks him to stop at the liquor store so he can pick up his booze.Also, some people may require him to take them to
      very undesirable places such as night clubs or places of that sort. Is it permissible to
      do a job that requires such things?
Praise be to Allah.We put this question to Shaykh Muhammad ibn Saalih al-Uthaymeen:
    one of our brothers in Canada is working as a taxi driver, and says that often, after
    taking on a passenger and commencing the journey, the passenger asks him to stop near a
    liquor store so that he can buy something from there. Some passengers also ask him to take
    them to places such as nightclubs. Is it permissible for him to work in this occupation or
    to accept these fares?
The shaykh, may Allaah preserve him, replied as follows:
No, it is not permissible for him to stop at the liquor store for his
    passenger to buy some, and it is not permissible for him to take anyone to forbidden
    clubs, because Allaah says (interpretation of the meaning):  Help you one
    another in al-birr and al-taqwa (virtue, righteousness and piety); but do not help one
    another in sin and transgression [al-Maaidah 5:2].
And Allaah knows best.
