Ruling on concluding a marriage contract in a church

Q 29: Is it permissible to conclude a marriage contract in a church? Is it permissible to write the marriage contract twice, once in the Islamic way and the other in the Christian way to satisfy both parties?

(Part No. 18; Page No. 97) A: It is impermissible to conclude a marriage contract in a church. The Islamic contract is enough; and the other contract is nullified. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
