To work in guarding churches, liquor

Q: Is it permissible for a Muslim employed as a builder to build churches for Kafirs (disbelievers)?

A: It is not lawful for a Muslim, who believes in Allah and the Last Day, to build a church or any place of worship that is not founded on the Islam with which Allah sent Muhammad (peace be upon him). This is because it is one of the most major ways of supporting Kufr (disbelief) and displaying its rituals. Allah (Glorified and Exalted be He) says in this regard (what means): Help you one another in Al-Birr and At-Taqwâ (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allâh. Verily, Allâh is Severe in punishment. (Part No. 14; Page No. 483) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
