‘Uqbah bin ‘Amir (May Allaah be pleased with him) reported:

The Messenger of Allaah (salla llaahu ‘alaihi wa sallam) 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 (Allaah) the Rabb of the daybreak’ (Surah 113), and ‘Say: I seek refuge with (Allaah) the Rabb of mankind’ (Surah 114).”
