Halloween is an annual western celebration in the late evenings of October 31st, which has its origination from early Celtic and European pagan doctrines. The Halloween celebrations root back to Celtic festival Samhain (pronounced sah-win) . Samhain is the celebration of the end of harvest and store the harvest for the oncoming winter in the Gaelic culture.
The Gaelics also believe on the evening of the October 31st the dead revisit the living, as an overlap of the boundaries between two worlds of the living and dead. The beliefs were also based that the return of the deceased can result in havoc and damage to crops and sickness spreading. To protect themselves from danger, they would dress in elaborate costumes under the belief that the dead would not be able to recognise them.
The trick-or-treating originated from the medieval practice of ‘souling’, where the poor visit from door to door praying for the dead, for which in return they get food. The bottom line is that Halloween is the representation of the devil worshipers. Muslims celebrating Halloween is 100% Haram and sinful, as it is involving the fundamentals of polytheism.
Further, the present Halloween celebrations, whther it be trick-or-treating, wearing weird costumes, carving jack-o-lanterns (which absolutely is a waste of pumpkins), decorating your home with witches, spider nets, artificial inks to represent blood etc. and also abhorrent behaviour of both adults and children in costumes as monsters and witches. Muslims should not celebrate or participate in the celebrations of Halloween.
Muslims who live in a Halloween celebrating neighbourhood would have the hardest time, leaving them thinking they have no option but to participate when children from the neighbourhood come come knocking at their doors. We should not indulge in haram activities, but we still need to associate and live with people of different beliefs.
You can send a short note around to your neighbourhood before the Halloween date arrives, advising your neighbours that you do not participate in the celebration, and outline to them the reasons why it is not in conformity with the Islamic beliefs.
To keep up the spirits of your own children and to show you still have a lot to enjoy, you can plan some in-house activities with your whole family, either family games or taking your children to a local mosque gathering where they can involve themselves in games or religious talk that can benefit them.
We should also perceive the fact that even some Christians and Jews refrain from Halloween celebrations as it unduly exalts the ghosts and spirits, and there are even Atheists who avoid Halloween because they recognise the blatant consumerism involved. So Muslims should not feel that they are alone in avoiding these Pagan rituals masquerading as modern holidays.
