A molvi says that to join in the cultural celebrations of non-Muslims is permissible as long as there will be no wine and other haraam acts.

Answer

Participation in kuffaar celebrations is per se Haraam even if we assume that there will be no wine, dancing, music, etc. Rasulullah (Sallallahu alayhi wasallam) said: "Whoever emulates a nation is of them."

The fellow who had answered the question is a kuffaar bootlicker. Not only are religious celebrations haraam, even the cultural celebrations of kuffaar are haraam.

When Rasulullah (Sallallahu alayhi wasallam) was informed that the Yahood also fasted on 10th Muharram, he ordered Muslims to add one more day in order to avoid Tashabbuh of the Yahood. Rasulullah (Sallallahu alayhi wasallam) ordered Muslims who don Amaamah to have topis under their Amaamahs. This was to avoid imitation of the Yahood who wore turbans without topis.

Those who participate in kuffaar functions and celebrations are regarded to be among the kuffaar.

This issue is exceptionally simple to understand. Only a person whose Imaan is corrupted with kufr is dense in the brains to understand an issue which requires no daleel.
