Riyad as-Salihin

'Uqbah bin 'Amir (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said: "Do you not know that last night certain Ayat were revealed the like of which there is no precedence. They are: 'Say: I seek refuge with (Allah) the Rubb of the daybreak' (Surah 113), and 'Say: I seek refuge with (Allah) the Rubb of mankind' (Surah 114)."
