Hazrat Zirr narrates that I asked Hazrat Ubayy: Hazrat Ibn Mas'ud did not write the Mu'awwidhatayn (the last two surahs of the Qur'an) in his manuscript and said: I asked the Prophet (peace and blessings be upon him) about these two surahs, and he (peace and blessings be upon him) said: These were given to me to recite, so I recited them. Hazrat Ubayy replied: And we recite them as we have been commanded.

Hazrat Husain narrates that Imam Sha’bi said: The Mu’awwidhatayn are a part of the Qur’an.

The statement of Imam Sha'bi similar to the previous one is narrated from Hazrat Husain with this chain of transmission.

Hazrat Abdur Rahman bin Yazid narrates that I saw Hazrat Abdullah bin Masood (may Allah be pleased with him) scraping and erasing the Mu'awwidhatayn from his manuscripts, and he said: Do not mix into the Qur'an that which is not from it.

Ibrahim narrates that I asked Hazrat Aswad: Are these two (chapters) part of the Qur'an? He replied: Yes! Meaning the Mu'awwidhatayn.

Hazrat Salman, who is the freed slave of Umm Ali (may Allah be pleased with her), narrates that indeed Hazrat Mujahid disliked reciting only the Mu'awwidhatayn alone. Rather, he would combine another Surah with them.

Hazrat Muhammad bin Salim narrates that I said to Hazrat Abu Ja'far: Indeed, Hazrat Ibn Mas'ud had erased the Mu'awwidhatayn from the manuscripts! So he replied: You should recite both of them.

Hazrat Mansur Qassab narrates that I asked Hasan: O Abu Saeed! Can I recite the Mu'awwidhatayn in the Fajr prayer? He replied: Yes, if you wish, these two are very blessed and pure Surahs.

Hazrat Uqbah bin Amir narrates that he asked the Messenger of Allah (peace and blessings be upon him) about the Mu'awwidhatayn. He states: So the Prophet (peace and blessings be upon him) led us in the Fajr prayer with these two Surahs.

Hazrat Uqbah bin Amir narrates that I was on a journey with the Messenger of Allah, peace and blessings be upon him. When the true dawn appeared, I gave the call to prayer (adhan) and the iqamah. Then the Prophet, peace and blessings be upon him, made me stand on his right side and recited the Mu'awwidhatayn (the two chapters of seeking refuge). When the prayer was finished, the Prophet, peace and blessings be upon him, said: Did you see what I recited? I said: O Messenger of Allah (peace and blessings be upon him)! Indeed, I saw. The Prophet, peace and blessings be upon him, said: Recite these two surahs whenever you go to sleep and whenever you wake up.
