Abu 'Abdullah narrated that Ibn 'Aabis Al-Juhani told him that: The Messenger of Allah ﷺ said: "O Ibn 'Aabis, shall I not tell you of the best thing with which those who seek refuge with Allah may do so?" He said: "Yes, O Messenger of Allah." He said: "Say: I seek refuge with (Allah) the Lord of the daybreak.", "Say: I seek refuge with (Allah) the Lord of mankind." - these two Surahs." Reference: Sunan an-Nasa'i 5432 .
