Is voting for a non-Muslim political party permissible?

Answer

Participation in non-Muslim politics is not permissible. Voting for non-Muslim and even secular Muslim parties is not normally permissible. However, in certain circumstances it becomes permissible. For example, if a particular party is anti-Muslim and its policy is to harm Muslims if it comes to power, then it will be permissible to vote for the other party which is not a danger to the Muslim community such as the situation in India where the Hindu verkrampte party (BJP) has stated its intention of forcibly converting Muslims to Hinduism and converting all the Musaajid into Hindu temples of idol worship.
