Allah informs about the approach of the Last Hour and the imminent end and demise of the world,

﴿أَتَى أَمْرُ اللَّهِ فَلاَ تَسْتَعْجِلُوهُ﴾

(The Event ordained by Allah will come to pass, so seek not to hasten it.)(16:1),

﴿اقْتَرَبَ لِلنَّاسِ حِسَـبُهُمْ وَهُمْ فِى غَفْلَةٍ مُّعْرِضُونَ ﴾

(Draws near for mankind their reckoning, while they turn away in heedlessness.)(21:1)
