Establishing Islamic parties in secular countries

Q 9: Is it permissible to establish Islamic parties in secular states where they are officially subject to secular laws, but their objective is to practice Da`wah secretly?

A: It is prescribed for Muslims who live in non-Islamic states to unite, cooperate, and work together, whether in the name of Islamic parties or Islamic societies, for it is cooperating in righteousness and piety.
