Atoms can be divided
34:3 ►“ وَقَالَ الَّذِينَ كَفَرُوا لا تَأْتِينَا السَّاعَةُ قُلْ بَلَى وَرَبِّي لَتَأْتِيَنَّكُمْ عَالِمِ الْغَيْبِ لا يَعْزُبُ عَنْهُ مِثْقَالُ ذَرَّةٍ فِي السَّمَاوَاتِ وَلا فِي الأرْضِ وَلا أَصْغَرُ مِنْ ذَلِكَ وَلا أَكْبَرُ إِلا فِي كِتَابٍ مُبِينٍ “
“ The Unbelievers say, “Never to us will come the Hour”: Say, “Nay! but most surely, by my Lord, it will come upon you;- by Him Who knows the unseen,- from Whom is not hidden the least little atom in the heavens or on earth: Nor is there anything less than that, or greater, but is in the Record Perspicuous “ [Al-Qur'an- Surah Saba 34:3]
This verse also refers to the Omniscience of God, His knowledge of all things, hidden or apparent. It then goes further and says that God is aware of everything, including what is smaller or bigger than the atom. Thus the verse clearly shows that it is possible for something smaller than the atom to exist, a fact discovered only recently by modern science.
1 A similar message is conveyed in the Qur’an in 10:61.
