Re: Halloween and other occasions
Yes, Halloween by origin was a Pagan ritual. Some people will tell you it is the American version of Mexico’s “Day of the Dead” but its roots go several millenia further back.
Now, I’m no scholar so I can’t say my answer is definitely right, but if you know what you’re doing is only out of goodness with no poor intentions, then you should be fine. On the other hand, Islam teaches us to stay away from things in which we’re not sure of. I’ll admit that I went out for Halloween. We don’t go out often but I do take my wife out to make her happy especially when my siblings are out as well. That to me is a sufficient reason though it may be argued.
It really comes down to what you’re comfortable with and your level of knowledge of both Islam and history. I would recommend seeking answers to questions like these through renowned scholars like Sheikh Hazma Yusuf, Yusuf Estes, or Imran Hosein, among many others of course.
A word of advice though, Muslims are supposed to stand out, not blend in with the crowd. Remember that we’re supposed to be role models for society without ever having to even open our mouths. Don’t do things just because your neighbors do, you’re a Muslim first, an American second.
