The Ruling on Celebrating the Festivals of the Christians

Question:
Honorable Shaykh, may Allah grant you success, you mentioned (may Allah preserve you) that one must be wary of the trials that have spread and become widespread. Among those trials in these days is the joy over the Christians' festival in completing the year two thousand, and the celebration thereof by some Muslims. What is your guidance, Honorable Shaykh (may Allah preserve you)?

Answer:
It is not permissible to participate with the disbelievers in their festivals, nor is it permissible to encourage them, attend them, or eat the food prepared for them. Rather, it is obligatory to denounce them and stay away from them.
Allah the Exalted said: The scholars interpreted al-zur (the falsehood) as the festivals of the disbelievers, meaning that one does not attend them. So the Muslim does not attend the festivals of the disbelievers, nor does he participate in them, nor does he encourage them, nor does he congratulate them, nor does he offer them congratulations on them, nor does he eat from the food they prepare for them, or send them gifts on the occasion, or accept their gifts on the occasion. Then it is obligatory for the Muslim to completely boycott the festivals of the disbelievers, because this is part of al-wala' wa al-bara' (loyalty and disavowal), and disavowal of the mushrikin (those who associate partners with Allah), and disavowal of the disbelievers and their deeds. Yes.
