What some sisters have said to you, that this action
is something that is not permitted, is correct, because it involves
imitating the kuffaar in two ways.
Firstly it involves celebrating this festival, which
is something that is haraam according to sharee’ah, including offering
gifts on this festival.
Secondly, it involves imitating the kaafirs in these
customs on the day of their celebration of that innovated festival.
In Islam we have only Eid al-Fitr and Eid al-Adhaa. Any
other festivals that have been innovated besides these two amount to
nothing, especially if they are the religious festivals of other religions
or groups that are beyond the pale of Islam.
Please see Question no. 947
This matter opens the door to bid’ah, and it comes under the general meaning of the words of the Prophet
(peace and blessings of Allaah be upon him), “Whoever innovates anything in this matter of ours that is not part of it will have it rejected.” (Narrated by al-Bukhaari, al-Sulh 2499; Muslim, 1718). And Allaah knows best.
