Assalaamu Alaykum, Please answer my question Mufti Saheb. I am the only muslim in my office and the rest are Christians. On the 25th December one of them decided to have a get together in the office and ordered pizza. I proposed to pay for my pizza as I knew that the get together was for christmas. But the host declined and I ate along with them. I want to ask whether I have comitted Kufr as this get together was for Christmas? And do I have to renew my Nikah?
Though this participation was not right, you should avoid it in future, but renewing the Nikah will not be required on the accounts the activities you did there. Yes, if you performed some other things, then you should ask the question again writing it clearly.
Allah (Subhana Wa Ta’ala) knows Best
