Salam, in the Quran it says Judgement day will be like a 1000 years of our reckoning, in an Islamic youtube video it was mentioned that for the Believers this time will pass like the hours between dhuhr and asr. Is this authentic?
Alaikumassalam wa rahmatullah,
The Quran doesn’t say that. It says a day in God’s view is similar to 1000 years of ours, it is not related to the Day of Judgment. But it seems likely to me that once we die, we wake on the Day of Judgment feeling like just a few hours have passed, even if tens of thousands of years have passed in the world until the Day of Judgment.
