We know only what Allah has told us but we can’t elaborate on the nature of such a thing as it is unseen to us and it is beyond our comprehension.

Things will change and be different to what we know. Allah says: “And they ask you to hasten on the torment! And Allâh fails not His Promise. And verily, a day with your Lord is as a thousand years of what you reckon”22:47

This means that only Allah knows about the nature of such days, whether 1,000 or 50,000 years.

I’ve heard that the lenght of the Day of Resurrection would be 50000 years. Will each year there be equal to 365 days? Do each and every people that day would have to wait for 50000 years, or some would get to wait less than that?
