Knower of the unseen in the Holy Quran

﴿وَقَالَ ٱلَّذِينَ كَفَرُواْ لَا تَأۡتِينَا ٱلسَّاعَةُۖ قُلۡ بَلَىٰ وَرَبِّي لَتَأۡتِيَنَّكُمۡ عَٰلِمِ ٱلۡغَيۡبِۖ لَا يَعۡزُبُ عَنۡهُ مِثۡقَالُ ذَرَّةٖ فِي ٱلسَّمَٰوَٰتِ وَلَا فِي ٱلۡأَرۡضِ وَلَآ أَصۡغَرُ مِن ذَٰلِكَ وَلَآ أَكۡبَرُ إِلَّا فِي كِتَٰبٖ مُّبِينٖ ﴾ [Saba’: 3]

(3) But those who disbelieve say, "The Hour will not come to us." Say, "Yes, by my Lord, it will surely come to you. [Allah is] the Knower of the unseen." Not absent from Him is an atom's weight within the heavens or within the earth or [what is] smaller than that or greater, except that it is in a clear register -
