It was narrated that 'Uqbah bin 'Amir said:

"I was walking with the Messenger of Allah ﷺ and he said: "O 'Uqbah, say!' I said: 'What should I say, O Messenger of Allah?' He did not answer me, then h esaid: 'O 'Uqbah, say!' I said: 'What should I say, O Messenger of Allah?' But he did not answer me. I said: 'O Allah, make him answer me.' He said: 'O 'Uqbah, say!' I said: 'What should I say, O Messenger of Allah?' He said: 'Say: I seek refuge with (Allah) the Lord of the daybreak...' So I recited it until I came to the end. Then he said: 'Say,' and I said: 'What should I say, O Messenger of Allah?' He said: 'Say: I seek refuge with (Allah) the Lord of mankind...,' so I recited it until I came to the end. Then the Messenger of Allah ﷺ said: 'No one who asks has ever asked by means of anything like them, and no one who seeks refuge has ever sought refuge with anything like them.'"
