Is it permissible to attend a Halloween costume party? 

Answer: Virtually all Halloween traditions are based either in an ancient pagan culture, or Christianity. From an Islamic point of view, they all are forms of idolatry (shirk). As Muslims, our celebrations should be ones that honour and uphold our faith and beliefs. How can we worship only Allah, the Creator, if we participate in activities that are based in pagan rituals, divination, and the spirit world? 

Celebrating Halloween in any form is impermissible and against the teachings of Islam.

Rasulullah (صلى الله عليه وسلم) said, 

مَنْ تَشَبَّهَ بِقَوْمٍ فَهُوَ مِنْهُمْ

“The one who imitates any people is amongst them.” [Abu Dawood]

The famous Sahabah, Abdullah ibn Amr (رضي الله عنهما) adds,

مَنْ بَنَى فِي بِلَادِ الْأَعَاجِمِ فَصَنَعَ نَوْرُوزَهُمْ وَمِهْرَجَانَهُمْ وَتَشَبَّهَ بِهِمْ حَتَّى يَمُوتَ وَهُوَ كَذَلِكَ حُشِرَ مَعَهُمْ يَوْمَ الْقِيَامَةِ

 “Whoever resides in the lands of the non-Arabs and then celebrates their religious occasions (such as Nairuz and Mihrajan – Persian holidays) and emulates their practices and thereafter dies in such a condition, shall be raised with them on the Day of Judgement.” Sunnan Kubra 

And Almighty Allah Knows Best
