Responding to your question about Halloween in Islam, Dr. Muzzammil Siddiqi, Former President of the Islamic Society of North America (ISNA), states:
However, there are still many Christians who resent it and consider it a bad holiday. Some of them even call it a “helliday.”
Whether Christians accept it or not, we Muslims should not accept this holiday. It is meaningless.
Wearing costumes, going tricking and treating and decorating houses with witches, spider nets and wasting so much pumpkins, etc., are all repugnant things.

Some people really act like monsters and witches. Muslims should not participate in this holiday.
Allah Almighty knows best.
