One of his most famous narrations concerns the last two surahs of the Qur'an.
ʿUqbah ibn ʿĀmir reported, The Messenger of Allah ﷺ said:
"Have you not seen verses revealed tonight the like of which has never been seen?
'Say: I seek refuge in the Lord of Daybreak'
'Say: I seek refuge in the Lord of Mankind.'
He also narrated that The Prophet ﷺ instructed him:
"Recite the two surahs of seeking refuge after every prayer."
Imam Ahmad recorded from Zirr bin Hubaysh that Ubayy bin Ka`b told him that Ibn Mas`ud did not record the Mu`awwidhatayn in his Mushaf (copy of the Qur'an). So Ubayy said, "I testify that the Messenger of Allah ﷺ informed me that Jibril said to him,
Say: "I seek refuge with the Lord of Al-Falaq.
So he said it. And Jibril said to him,
Say: "I seek refuge with the Lord of mankind."
So he said it. Therefore, we say what the Prophet said."
In his Sahih, Muslim recorded on the authority of `Uqbah bin `Amir that the Messenger of Allah ﷺ said,
Do you not see that there have been Ayat revealed to me tonight the like of which has not been seen before
They are:
Say: "I seek refuge with, the Lord of Al-Falaq."
and
Say: "I seek refuge with the Lord of mankind.
This Hadith was recorded by Ahmad, At-Tirmidhi and An-Nasa'i.
In Another Narration
Imam Ahmad recorded from `Uqbah bin `Amir that he said, "While I was leading the Messenger of Allah ﷺ along one of these paths he said,
"O `Uqbah! Will you not ride"
I was afraid that this might be considered an act of disobedience. So the Messenger of Allah ﷺ got down and I rode for a while. Then he rode. Then he said,
(O `Uqbah! Should I not teach you two Surahs that are of the best two Surahs that the people recite) I said, `Of course, O Messenger of Allah.' So he taught me to recite
Then the call was given to begin the prayer and the Messenger of Allah ﷺ went forward (to lead the people), and he recited them in the prayer. Afterwards he passed by me and said,
What do you think, O `Uqayb Recite these two Surahs whenever you go to sleep and whenever you get up
Record in An-Nasa'i and Abu Dawud
In Another Narration, An-Nasa'i recorded that `Uqbah bin `Amir said, "I was walking with the Messenger of Allah ﷺ when he said,
O `Uqbah! Say!
I replied, `What should I say' So he was silent and did not respond to me. Then he said,
(Say!) I replied, `What should I say, O Messenger of Allah' He said,
(Say: "I seek refuge with the Lord of Al-Falaq.") So, I recited it until I reached its end. Then he said,
(Say!) I replied, `What should I say O Messenger of Allah' He said,
(Say: "I seek refuge with the Lord of mankind.") So, I recited it until I reached its end. Then the Messenger of Allah ﷺ said,
No person beseeches with anything like these, and no person seeks refuge with anything like these.
In another authentic naration where An-Nasa'i recorded that Ibn `Abis Al-Juhani said that the Prophet said to him
O Ibn `Abis! Shall I guide you to -- or inform you -- of the best thing that those who seek protection use for protection
He replied, "Of course, O Messenger of Allah!", The Prophet said,
Say: "I seek refuge with the Lord of Al-Falaq.")( and (Say: "I seek refuge with the Lord of mankind.")( These two Surahs (are the best protection)
Imam Malik recorded from `A'ishah that whenever the Messenger of Allah ﷺ was suffering from an ailment, he would recite the Mu`awwidhatayn over himself and blow (over himself). Then if his pain became severe, `A'ishah said that she would recite the Mu`awwidhatayn over him and take his hand and wipe it over himself seeking the blessing of those Surahs. Al-Bukhari, Abu Dawud, An-Nasa'i and Ibn Majah all recorded this Hadith.
At-Tirmidhi, An-Nasa'i and Ibn Majah recorded this. At-Tirmidi said this is a Hasan Sahih hadith. "It has been reported from Abu Sa`id that the Messenger of Allah ﷺ used to seek protection against the evil eyes of the Jinns and mankind. But when the Mu`awwi- dhatayn were revea- led, he used them (for protection) and abandoned all else besides them."
