The ruling on attending the festivals of the disbelievers and congratulating them

Question:
In the case of the Honorable Shaykh, there is also a question that perhaps has not been raised yet, and it concerns, may Allah preserve you, the issue of festivals in Western countries. Is it permissible for a Muslim to attend them and participate in them, or to congratulate the disbelievers on them, or anything of that sort?

Answer:
It is not permissible to attend the festivals of the disbelievers, nor is it permissible to congratulate them on them, because they are invalid. Allah, Mighty and Majestic, says: And falsehood is the festivals of the disbelievers. They do not witness them, meaning they do not attend them, because if you attend them, you encourage them in them and agree with them on them. Likewise, if you congratulate them on them, you endorse them and encourage them in them, and you cooperate with them in falsehood. Therefore, it is not permissible to participate in the festivals of the disbelievers in any way, because they are invalid festivals, festivals of disbelief. Yes.
