Halloween is a festival which originates from Ireland. from an Islamic perspective halloween has no basis at all and thus the day is of no significance at all. If people who celebrate this day cause any disturbance, we must tolerate this with due respect and patience. However, we must refrain on all accounts from indulging in any kind of celebration etc. please refer to the Hadith listed below:
'whoever imitates a people, then he is from among them'.
