If a muslim works at a school and a note/message was sent around asking work colleagues if they wanted to come to the Christmas dinner. The Muslim fills in the attendance form to attend the dinner and gives money for the dinner.
The Muslim atttends as he didnt want to be rude, offend the Staff by not going. He also attended because he wanted to fit in with the rest of the work colleagues, he did not want to show any disrespect so he attended the dinner and he did not want anyone to say that he hasn’t turned up to the dinner and he did not want to come across impolite.
Has he become a kafir/murtad for going to the Christmas dinner and going to the Christmas dinner for any of the above reasons and any of the above explanation?The Muslim has and had no belief in Christmas.
