The Prophet ﷺ said, "The Hour (Last Day) will not be established until (religious) knowledge will be taken away (by the death of religious learned men), earthquakes will be very frequent, time will pass quickly, afflictions will appear, murders will increase and money will overflow amongst you." (See Hadith No. 85 Vol 1).  

قَالَ النَّبِيُّ ﷺ لاَ تَقُومُ السَّاعَةُ حَتَّى يُقْبَضَ الْعِلْمُ وَتَكْثُرَ الزَّلاَزِلُ وَيَتَقَارَبَ الزَّمَانُ وَتَظْهَرَ الْفِتَنُ وَيَكْثُرَ الْهَرْجُ وَهْوَ الْقَتْلُ الْقَتْلُ حَتَّى يَكْثُرَ فِيكُمُ الْمَالُ فَيَفِيضُ  

(The Prophet) said, "O Allah! Bless our Sham and our Yemen." People said, "Our Najd as well." The Prophet again said, "O Allah! Bless our Sham and Yemen." They said again, "Our Najd as well." On that the Prophet ﷺ said, "There will appear earthquakes and afflictions, and from there will come out the side of the head of Satan."  

اللَّهُمَّ بَارِكْ لَنَا فِي شَامِنَا وَفِي يَمَنِنَا قَالَ قَالُوا وَفِي نَجْدِنَا قَالَ قَالَ اللَّهُمَّ بَارِكْ لَنَا فِي شَامِنَا وَفِي يَمَنِنَا قَالَ قَالُوا وَفِي نَجْدِنَا قَالَ قَالَ هُنَاكَ الزَّلاَزِلُ وَالْفِتَنُ وَبِهَا يَطْلُعُ قَرْنُ الشَّيْطَانِ
