things smaller than an atom (originally meant as "ant"?)

وَمَا تَكُونُ فِى شَأْنٍ وَمَا تَتْلُوا۟ مِنْهُ مِن قُرْءَانٍ وَلَا تَعْمَلُونَ مِنْ عَمَلٍ إِلَّا كُنَّا عَلَيْكُمْ شُهُودًا إِذْ تُفِيضُونَ فِيهِ ۚ وَمَا يَعْزُبُ عَن رَّبِّكَ مِن مِّثْقَالِ ذَرَّةٍ فِى ٱلْأَرْضِ وَلَا فِى ٱلسَّمَآءِ وَلَآ أَصْغَرَ مِن ذَٰلِكَ وَلَآ أَكْبَرَ إِلَّا فِى كِتَـٰبٍ مُّبِينٍ

In whatever matter you [Prophet] may be engaged and whatever part of the Quran you are reciting, whatever work you [people] are doing, We witness you when you are engaged in it. Not even the weight of a speck of dust in the earth or sky escapes your Lord, nor anything lesser or greater: it is all written in a clear record.

وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَا تَأْتِينَا ٱلسَّاعَةُ ۖ قُلْ بَلَىٰ وَرَبِّى لَتَأْتِيَنَّكُمْ عَـٰلِمِ ٱلْغَيْبِ ۖ لَا يَعْزُبُ عَنْهُ مِثْقَالُ ذَرَّةٍ فِى ٱلسَّمَـٰوَٰتِ وَلَا فِى ٱلْأَرْضِ وَلَآ أَصْغَرُ مِن ذَٰلِكَ وَلَآ أَكْبَرُ إِلَّا فِى كِتَـٰبٍ مُّبِينٍ

Still, the disbelievers say, ‘The Last Hour will never come upon us.’ Say, ‘Yes, by my Lord, [it will], by Him who knows the unseen! Not even the weight of a speck of dust in the heavens or earth escapes His knowledge, nor anything smaller or greater. It is all recorded in a clear Record
