What happens if al aksa mosque was destroyed some people say that it is a sign of yawm al qiyamah and the Quran will have no words only empty pages and all the good stuff you do will not count?

Answer 1

It's a building. Presumably some people would be upset if it were destroyed, but it's not "magic".

Answer 2

The destruction of any religious site, including Al Aqsa Mosque, would be a devastating event for the Muslim community. However, speculations about its impact on the Day of Judgment (Yawm al-Qiyamah) or the Quran are not based on Islamic teachings. Good deeds are expected to be rewarded regardless of any physical destruction, as their value lies in the intentions and actions of individuals.
