Celebrar o Halloween: é haram?

Islam's majority ruling on Halloween participation is prohibition, built on two pillars. The first is the imitation principle: 'whoever imitates a people is one of them' (Abu Dawud 4031), which jurists apply to distinctive religious festivals of other communities — and Halloween, whatever its secular American shell, retains distinctively non-Islamic religious bones (All Saints', All Souls', spirit-lore about the dead returning). The second is theological: the holiday's themes — ghosts, contacting or warding spirits, celebrating macabre death — sit poorly with a tradition that holds the dead in the barzakh, beyond contact, and forbids fear-based superstition (the Prophet abolished omen-taking). Add the Quran's warning that other communities are not pleased until the believer follows their religion (2:120), and the standard fatwa conclusion follows: don't celebrate it, don't decorate for it, and gently explain to the children why — with alternatives (Muslim families increasingly host fall festivals or 'halal-ween' game nights). The minority accommodations: a Muslim may give candy to children who knock (courtesy to neighbors is commanded; turning them away harshly harms dawah), and some scholars permit children's participation in school costume events as unavoidable environment rather than chosen observance. The tradition's own festival calendar — the two Eids — is the identity anchor.
