It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: Are you incapable of reciting one third of the Noble Qur'an in a single night? This was difficult for the companions, and they said: Who has the strength to do this action? He (peace and blessings be upon him and his family) said: Recite {قُلْ ھُوَ اللّٰہُ اَحَدٌ}, for it is one third of the Qur'an.

Sayyiduna Abu Mas’ud Badri Ansari (may Allah be pleased with him) also narrates a similar hadith from the Noble Prophet (peace and blessings be upon him).

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Gather together, I am going to recite to you one third of the Holy Qur'an. When those who were to gather had gathered, he (peace and blessings be upon him) came out and recited {قُلْ ھُوَ اللّٰہُ اَحَدٌ}, then he went inside. We began to say to one another: Some news has come from the sky, because of which he has gone inside. Then he (peace and blessings be upon him) came out and said: I had told you that I would recite one third of the Holy Qur'an to you, and this surah is equal to one third of the Qur'an (which I have recited to you).

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) heard a man reciting {قُلْ ھُوَ اللّٰہُ اَحَدٌ} until he completed this Surah. The Prophet (peace and blessings be upon him) said: "It has become obligatory." Someone asked: "O Messenger of Allah! What has become obligatory?" He (peace and blessings be upon him) replied: "Paradise has become obligatory." Sayyiduna Abu Hurairah (may Allah be pleased with him) said: "I intended to give this reciter the glad tidings, but I preferred to eat with the Noble Prophet (peace and blessings be upon him), fearing that I might miss the opportunity to eat with the Messenger of Allah (peace and blessings be upon him). But after eating, when I went to that man, he had already left."

Narrated by Sayyiduna Mu'adh bin Anas al-Juhani, may Allah be pleased with him: The Noble Prophet, peace and blessings be upon him, said: Whoever recites {قُلْ ھُوَ اللّٰہُ اَحَدٌ}, that is, Surah Al-Ikhlas, to the end ten times, Allah Almighty will build a palace for him in Paradise. Sayyiduna Umar, may Allah be pleased with him, said: O Messenger of Allah! Then I can have many palaces. The Prophet, peace and blessings be upon him, said: Allah Almighty is even more abundant and the bestower of excellent gifts.

Narrated by Sayyiduna Abu Mas’ud Ansari (may Allah be pleased with him): The Noble Prophet (peace and blessings be upon him and his family) said: Surah Al-Ikhlas is equal to one third of the Noble Qur’an.

It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him), he says: The Noble Prophet (peace and blessings be upon him) met me, he (peace and blessings be upon him) initiated the greeting of peace and said: O Uqbah bin Amir! Shall I not teach you the best three Surahs that were revealed in the Torah, the Gospel, the Psalms, and the Noble Qur’an? I said: May Allah sacrifice me for you, certainly tell me. Then he (peace and blessings be upon him) taught me Surah Ikhlas, Surah Falaq, and Surah Nas and said: O Uqbah! Do not forget them and do not spend any night except that you recite them in it. Since the time he (peace and blessings be upon him) advised me not to forget them, I have not forgotten them, nor have I spent any night except that I have recited them in it.

It is narrated from Sayyiduna Abdullah bin Khubaib, he says: We were extremely thirsty, and it was dark, and we were waiting for the Noble Prophet (peace and blessings be upon him) so that he (peace and blessings be upon him) would come and lead us in prayer. Then he (peace and blessings be upon him) arrived and took hold of my hand and said: Say. I remained silent. He (peace and blessings be upon him) again said: Say. I asked: O Messenger of Allah, what should I say? He (peace and blessings be upon him) said: When you reach the evening and the morning, recite Surah Ikhlas, Surah Falaq, and Surah Nas three times each; they will suffice you every day, twice.

Narrated by Sayyiduna Uqbah bin Amir (may Allah be pleased with him), he says: Once I was leading the mount of the Noble Prophet (peace and blessings be upon him) along a path passing through a mountain. Suddenly, the Prophet (peace and blessings be upon him) said to me: "O Uqbah! Why don't you ride?" I said nothing; in fact, out of reverence for the grandeur of the Prophet (peace and blessings be upon him), I did not wish to ride. But the Prophet (peace and blessings be upon him) again said: "O Uqayb! Why don't you ride?" Now I became afraid that this might be considered disobedience, so the Prophet (peace and blessings be upon him) dismounted and I rode for a short while. Then the Prophet (peace and blessings be upon him) mounted again and said: "O Uqayb! Shall I not teach you the two best Surahs which people recite?" I said: "Yes, absolutely, O Messenger of Allah!" So the Prophet (peace and blessings be upon him) taught me Surah Al-Falaq and Surah An-Naas. Meanwhile, the Iqamah for prayer was called, and the Noble Prophet (peace and blessings be upon him) advanced and recited these two Surahs in that prayer. Then he passed by me and said: "O Uqayb! How did you find (the excellence of these two Surahs, as I have recited them in prayer)?" Whenever you go to sleep and whenever you wake up, recite these Surahs.

It is narrated from Sayyiduna Uqbah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Two surahs have been revealed to me. In another narration, it is stated: Such verses have been revealed to me that no verses like them have been found; seek refuge through them. There is no other surah like them through which refuge may be sought.
