According to the Islamic calendar, neither of two EID’s of Muslims have arrived, so there isn’t a collective cause such as to explain why any of the 1.6 billion Muslims should be engaged in collective celebration.
Perhaps those Muslims celebrating today are all celebrating an event that they’ve all simultaneously have encountered? Perhaps Jumada al-Awwal 17, 1442 AH was the day millions of Muslims coincidentally, had news of a new child in their close family, a new job, new found wealth, became hafidh (memorisers of the entire Quran), or anything else of great blessing? But that seems statistically so unlikely as to be absurd, so it can’t be that.
Perhaps they’re just celebrating and giving thanks for a new day? But if that’s the case, surely they’d be celebrating every day as a new day, no?
Perhaps for those Muslims who live in the northern hemisphere, they’re simply celebrating the Winter solstice, the end of the shortest day of daylight and the beginning of lengthening daylight days? But if so, they’re 10 days too late, it was on yawm alithneen (monday) Jumada Al-Awwal 6, 1442 hijri (21st December 2020 – Gregorian calendar). But Jumada al-Awwal 17 saw no significant cosmological phenomenon happening on this day to merit any such celebration, so it can’t be that.
It can’t be Muslims are celebrating the reset of the Christian Gregorian calendar, as why would the reset of calendar designed to keep the Christian festival of Easter roughly the same time every year, be any cause of celebration for Muslims?
I mean, after all, the festival of Easter is just an invented holiday, not even commanded in (the compilation of Christian letters and second/third hand accounts known as) The Bible, to celebrate the Christian-alleged resurrection of Jesus (ﷺ) from the dead, something Muslims don’t believe happened, so can’t see any even remote interest Muslims would have for celebrating it.
So what could it be?
Nothing in the world has principally changed, the COVID pandemic is still raging (and spreading worse than ever before in the UK), so why any Muslim would be collectively celebrating an arbitrary day is beyond any realm to intellectually account for.
Could it be that some Muslims are just copying what Western/Westernised non-Muslim neighbours are doing?
No, surely not! Why would Muslims ever copy whatever arbitrary festivals or cultural practices other people are doing? It’s not like we don’t have a guide from the Creator of all existence as to what we should celebrate and be thankful for, and what is simply just an arbitrary human invention linked to pre-Islamic invented festivals of a people unenlightened by the Deen (way of life/worldview/ideology) of Islam, right?
Anas ibn Malik reported: The Messenger of Allah ﷺ, arrived in Medina during two days in which they were celebrating. The Prophet said, “What are these two days?” They said, “We would celebrate these two days in the time of ignorance.” The Prophet said, “Verily, Allah has replaced these two days with two better days: Eid al-Adha and Eid al-Fitr.”
