Quran 34:3 from Surah Saba on Divine Marvels.
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
English translation: But say those who disbelieve Not will come to us the Hour Say Nay by my Lord surely it will come to you (He is the) Knower (of) the unseen Not escapes from Him (the) weight (of) an atom in the heavens and not in the earth and not smaller than that and not greater but (is) in a Record Clear
