An Nasai

"It was raining and dark, and we were waiting for the Messenger of Allah (ﷺ) to lead us in prayer. Then the Messenger of Allah (ﷺ) came out to lead us in prayer and he said: 'Say.' I said: 'What should I say?' He said: 'Say: He is Allah, (the) One and Al-Mu'awwadhatain in the evening and in the morning, three times, and that will suffice you against everything.'"

"I was with the Messenger of Allah (ﷺ) on the road to Makkah when I found myself alone with the Messenger of Allah (ﷺ). I drew close to him and he said: 'Say.' I said: 'What should I say?' He said: 'Say.' I said: 'What should I say?' He said: 'Say: I seek refuge with (Allah) the Lord of the daybreak...' until he finished (the Surah), then he said: 'Say: I seek refuge with (Allah) the Lord of mankind...' until he finished it. Then he said: 'The people cannot seek refuge with Allah by means of anything better than these two.'"

"While I was leading the Messenger of Allah (ﷺ) on his mount on a military campaign, he said: 'O 'Uqbah, say!' I listened, then he said: 'O 'Uqbah, say!' I listened, then he said it a third time. I said: 'What should I say?' He said: 'Say: He is Allah, (the) One...' and he recited the Surah to the end. Then he recited: 'Say: I seek refuge with (Allah) the Lord of the daybreak...' and I recited it with him until the end. Then he recited: 'Say: I seek refuge with (Allah) the Lord of mankind...' and I recited it with him until the end. Then he said: 'No one ever sought refuge (with Allah) by means of anything like them.'"

"The Messenger of Allah (ﷺ) said to me: 'Say.' I said: 'What should I say?' He said: 'Say: He is Allah (the) One,' 'Say: I seek refuge with (Allah) the Lord of the daybreak,' 'Say: I seek refuge with (Allah) the Lord of mankind.' The Messenger of Allah (ﷺ) recited them, then he said: 'The people have never recited anything like them, or the people have never sought refuge (with Allah) by means of anything like them.'"

The Messenger of Allah (ﷺ) said to him: "O Ibn 'Abis, 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."

"The Prophet (ﷺ) was given a gray mule which he rode, and 'Uqbah led it. The Messenger of Allah (ﷺ) said to 'Uqbah: 'Recite.' He said: 'What should I recite, O Messenger of Allah?' He said: 'Recite: 'Say: I seek refuge with (Allah) the Lord of the daybreak, from the evil of what He has created.' And he repeated it until I had learned it."

He asked the Messenger of Allah (ﷺ) about Al-Mu'awwidhatain. 'Uqbah said: "The Messenger of Allah (ﷺ) recited them when he led us in Salah Al-Ghadah (As-Subh)."

The Messenger of Allah (ﷺ) recited them in the Subh prayer.

"I was leading the Messenger of Allah (ﷺ) (on his mount) on a journey, and the Messenger of Allah (ﷺ) said: 'O 'Uqbah, shall I not teach you the best two Surahs that can be recited?' And he taught me: 'Say: I seek refuge with (Allah) the Lord of the daybreak.' And 'Say: I seek refuge with (Allah) the Lord of mankind...' He thought that I did not seem too overjoyed with them, so when he stopped to pray Subh, he recited them when he led the people in the Subh prayer. When the Messenger of Allah (ﷺ) finished praying, he turned to me and said: 'O 'Uqbah, what do you think?'"
