It’s unfortunate that a pagan way of celebrating a day has become a norm and people all over the world celebrate it as their own.
This is the proof, that humans over a period of time when programmed for something continue to follow a culture without having any knowledge of it. They adopt it as their way of life, even if it doesn’t befit the one who submits his will to Allah. They participate wholesale even if the whole environment of celebrating is haram in itself.
That’s the irony of Muslims today and their way of Islam!
May Allah protect us from such deviated way of life which makes halal what Allah made haram and vice versa!
