Which Sura is considered as 1/3 of the Holy Quran? Answer: Surah Al-Ikhlas

Surah Al-Ikhlas (Chapter 112) is equal to one-third of the Quran. Prophet Muhammad (ﷺ) stated this in Sahih al-Bukhari 5015 because the surah perfectly summarizes Tawhid (the absolute oneness and attributes of Allah), which represents one of the three main thematic pillars of the Quran.
