Quran 16:77 An-Nahl, ayah 77 of 128

وَلِلَّهِ غَيْبُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ وَمَآ أَمْرُ ٱلسَّاعَةِ إِلَّا كَلَمْحِ ٱلْبَصَرِ أَوْ هُوَ أَقْرَبُ ۚ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ ۝٧٧

16:77 And unto Allah belongeth the Unseen of the heavens and the earth, and the matter of the Hour (of Doom) is but as a twinkling of the eye, or it is nearer still. Lo! Allah is Able to do all things.
