Decorating the Masjid minaret with Christian decoration
It is not permissible for Muslims to
imitate the disbelievers in their festivals, their places of worship and the like. The Prophet (peace be upon him) said:
Anyone who copies a people is one of them.
You must all avoid that and advise those who imitate them not to do. (Part No. 1; Page No. 465) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
