It is reported on the authority of Abu Hurairah (RA) that the Messenger of Allah ﷺ said: Get together. for I am going to recite one-third of the Quran before you. And those who could get together gathered there. Then the Apostle of Allah ﷺ came out and recited:" Say: He, Allah, is One." He then entered (his house). Some of us said to the others: Perhaps there has been some news from the heaven on account of which he has gone Inside (the house). The Apostle of Allah ﷺ again came out and said: I told you that I was going to recite one-third of the Quran; keep in mind, this (Surah Ikhlas) is equivalent to one-third of the Quran.
