What is the ruling on attending an annual company dinner called a Christmas dinner, which is devoid of Christmas rituals except for the exchange of gifts? And what if one is tasked with organizing this event?

It is not permissible for a Muslim to participate in the religious holidays of disbelievers, such as Christmas and its associated annual dinner, nor to congratulate them or offer them gifts on these occasions. This is because such actions involve aiding them in polytheism and showing approval of their deeds. A Muslim must apologize and employ stratagems to avoid such participation, as many companies respect the religious privacy of their employees.
