Asking such a question is not logical as Muslims believe in the unseen and it is our conviction that the Quran and sunnah are unquestionable.
Therefore, what remains here is questioning our own intellect which is not qualified to visualize and understand this as it is! We haven’t even seen the angels, how can we imagine how they come down or ascend?
This is something that we have to believe in it without being able to see it. no one knows when lailatul Qadr is and this knowledge is with Allah only.
