Hours and hours are passing. But all of this will end with final hour. Nobdy know which will be that final hour. Read Quran verse about final hour.

اعوذ بالله من الشيطان الرجيم

يَسْـَٔلُونَكَ عَنِ ٱلسَّاعَةِ أَيَّانَ مُرْسَىٰهَاۖ قُلْ إِنَّمَا عِلْمُهَا عِندَ رَبِّىۖ لَا يُجَلِّيهَا لِوَقْتِهَآ إِلَّا هُوَۚ ثَقُلَتْ فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِۚ لَا تَأْتِيكُمْ إِلَّا بَغْتَةًۗ يَسْـَٔلُونَكَ كَأَنَّكَ حَفِىٌّ عَنْهَاۖ قُلْ إِنَّمَا عِلْمُهَا عِندَ ٱللَّهِ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ 

They ask you, [O Muhammad], about the Hour: when is its arrival? Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the people do not know."

Al-Quran 7:187

My reflection on reading this Quran verse

No matter how advanced is the technology, nobody knows when the hour will be set. No forecast can get us ready. I wonder how people prepare in advance when there is a forecast for hurricane. But earthquakes come without warning. Don't we see all the signs of the nearness of hour. But still we have hope that it will be at least 40 years after Esa (asa) peace be on him will come back. But Allah says hour will be sudden, it will come unexpectedly, and nobody knows when it will come except Allah. Every travel reminds me of the hour because every travel requires so much preparation. And no matter how prepared I am, there are still last minute preparations. But Allah said hour will be sudden. But I am still in habit of last minute preparations. How will I manage? There are so many plans.
