Narrated Abu Huraira (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) said: "Every prophet was given such miracles that people believed in him because of them. And the miracle which has been given to me is the Revelation (the Qur'an) which Allah has revealed to me. (The effect of all previous miracles ended with time, but this miracle (the Qur'an) is everlasting.) So I hope that my followers will outnumber the followers of all other prophets on the Day of Resurrection."

Narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him): Allah sent down revelation to His Messenger (peace and blessings of Allah be upon him) frequently before his death, until near his death, revelation came in abundance. Then after that, the Messenger of Allah (peace and blessings of Allah be upon him) passed away.

Ameer-ul-Mu'mineen Umar bin Khattab (may Allah be pleased with him) says: I heard Sayyiduna Hisham bin Hakeem (may Allah be pleased with him) reciting Surah Al-Furqan during the blessed life of the Messenger of Allah (peace and blessings of Allah be upon him). I listened attentively and noticed that he was reciting it in several ways different from those in which the Messenger of Allah (peace and blessings of Allah be upon him) had taught me this Surah. (I became angry) and was about to attack him during the prayer itself, but I controlled myself. When he finished the prayer with salam, I put my cloak around his neck and asked, "Who taught you this Surah in the way I heard you recite it?" He replied, "The Messenger of Allah (peace and blessings of Allah be upon him) taught me." I said, "You are lying! The Messenger of Allah (peace and blessings of Allah be upon him) himself taught me this Surah in a different way." Then I dragged him to the Messenger of Allah (peace and blessings of Allah be upon him) and said, "O Messenger of Allah! I heard him reciting Surah Al-Furqan in a way you did not teach me." The Messenger of Allah (peace and blessings of Allah be upon him) said, "Let him go (and said), O Hisham! Recite." He recited it in the same way I had heard him recite. The Messenger of Allah (peace and blessings of Allah be upon him) said, "This Surah was revealed in this way." Then he said, "O Umar! Now you recite." I recited it in the way the Messenger of Allah (peace and blessings of Allah be upon him) had taught me, and he said, "It was revealed in this way as well. Indeed, this Qur'an has been revealed in seven ways (dialects), so recite in whichever way is easy for you."

Lady Fatimah al-Zahra (may Allah be pleased with her) says that the Messenger of Allah (peace and blessings be upon him) said to me quietly (in a low voice): "Jibreel (peace be upon him) used to review the Qur'an with me once every year, and this year he reviewed it twice. I think that the time of my death has approached."

`Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with both of them) says that By Allah, I have learned more than seventy surahs of the Qur'an directly from the blessed mouth of the Messenger of Allah (peace and blessings of Allah be upon him).

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that he was in (the Syrian city of) Homs. There he recited Surah Yusuf, so a person said, "This Surah was not revealed in the way you have recited it." Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said, "I recited this Surah before the Messenger of Allah (peace and blessings be upon him), and he said: 'You have recited very well.'" And (Sayyiduna Ibn Mas'ud, may Allah be pleased with him) perceived the smell of wine from his mouth, so he said: "On one hand, you deny the Book of Allah, and on the other, you enjoy the pleasures of wine?" Then he imposed the prescribed punishment on him.

Narrated by Sayyiduna Abu Sa'id Al-Khudri (may Allah be pleased with him):
A man heard someone reciting "(Qul Huwa Allahu Ahad)" (Surah Al-Ikhlas) repeatedly. In the morning, he came to the Messenger of Allah (peace and blessings be upon him) and mentioned this, as if he considered "(Qul Huwa Allahu Ahad)" to be little (in reward) due to its few words. The Messenger of Allah (peace and blessings be upon him) said: "By Him in Whose Hand is my soul! Verily, this Surah '(Qul Huwa Allahu Ahad)' is equal to one third of the Qur'an."

Narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said to his companions (by way of rhetorical question): "Is it difficult for any one of you to recite one third of the Qur'an in a single night?" This seemed difficult to them and they said, "O Messenger of Allah! Who among us has the strength to do that?" So he (peace and blessings of Allah be upon him) said: "Surah Al-Ikhlas, in which the attributes 'Allah is One, the Self-Sufficient' are mentioned, is equal to one third of the Qur'an."

Umm al-Mu’minin Aisha Siddiqa (may Allah be pleased with her) narrates that whenever the Prophet Muhammad (peace and blessings be upon him) would go to his bed every night, he would join his two palms together and recite (Qul Huwa Allahu Ahad), (Qul A’udhu bi-Rabbil-Falaq), and (Qul A’udhu bi-Rabbin-Nas) over them, then blow into them and wipe them over his entire body as far as he could reach. He would start by wiping his blessed head and face, and then the front part of his body, and he would do this three times.

Sayyiduna Usaid bin Hudair (may Allah be pleased with him) says that he was reciting Surah Al-Baqarah one night and his horse was tied near him. Suddenly, the horse began to startle. When he became silent, the horse calmed down. He started reciting again, and the horse startled again. He became silent again, and the horse calmed down. He started reciting again, and the horse startled again. Then he stopped (ceased recitation), and his son Yahya was lying near the horse. He feared that the horse might trample him. When he moved him from there and looked towards the sky, the sky was not visible. In the morning, he came and related this to the Noble Prophet (peace and blessings of Allah be upon him), so the Prophet (peace and blessings of Allah be upon him) said: "O Ibn Hudair! You should have continued reciting, O Ibn Hudair! You should have continued reciting." He said, "O Messenger of Allah! Yahya was lying near the horse, and I feared that the horse might trample Yahya, so I raised my head and returned to him. Then I raised my head towards the sky and saw a strange canopy-like cloud in which many lamps were lit. Then I went outside until it disappeared from my sight." The Prophet (peace and blessings of Allah be upon him) said: "Do you know what that was?" He said, "No." The Prophet (peace and blessings of Allah be upon him) said: "Those were angels who had come near you upon hearing your voice. If you had continued reciting till morning, other people would also have seen them (openly), and they would not have disappeared from their sight."
