Can he display gifts in his company to acknowledge Christmas?
Question

I work in a non-Muslim country and I have a company in which some non-Muslim people work. Can I buy some gifts to display in the company in acknowledgement of Christmas and as a token of participation on my part with them, or is this haram?
Praise be to Allah.It is not permissible to participate in Christmas festivities by offering gifts, taking time off work, putting up decorations, and the like. It is also not permissible to offer congratulations on the occasion of these festivals, because they are innovated and haram festivals that are connected to corrupt beliefs. Moreover, celebrating them is an imitation of the Christians, and that is emphatically haram, because the Prophet (blessings and peace of Allah be upon him) said: “Whoever imitates a people is one of them.” Narrated by Abu Dawood (4031); classed as saheeh by al-Albani in Irwa’ al-Ghaleel (5/109)
