that the Messenger of Allah (ﷺ) said: "Gather and I shall recite to you one third of the Quran." He said: "So whoever was to gather did so, then the Messenger of Allah (ﷺ) came out and recited Qul Huwa Allahu Ahad. Then he went back in. Some of them said to each other: "The Messenger of Allah (ﷺ) said: 'I shall recite to you one third of the Quran' I thought that this was news from the Heavens." Allah's Prophet (ﷺ) came out and said: "Indeed I said that I would recite to you one third of the Quran, and it is indeed equal to one third of the Quran."

Jami` at-Tirmidhi Book 45, Hadith 25 Next Hadith → "There was a man from the Ansar who led them (in Salat) at Masjid Quba. Every time he was to recite a Surah for them during Salat, he would begin by reciting Qul Huwa Allahu Ahad until he finished, then he would recite another Surah with it. He did that in each Rak'ah. His companions talked to him and said: 'You recite this Surah. You should either recite it or leave it and recite another Surah.'" He said: "I shall not leave it, if you would like me to lead you with it then I shall do so, and if you do not like it then I shall leave you." And they considered him the best among them, and they did not like the idea of someone else leading them. So when the Prophet (ﷺ) came to them they informed him about what had happened and he (ﷺ) said: "O so-and-so! What prevents you from doing what your companions told you to do, why do recite this Surah in every Rak'ah" He said: "O Messenger of Allah! Indeed I love it." So the Messenger of Allah (ﷺ) said: "Your love for it shall have you admitted into Paradise."
