Uthmaan bin Affaan (radiallaahu anhu) reported that the Messenger of Allaah (sallallaahu alaihi wasallam) said: "The best amongst you is the one who learns the Qur'aan and teaches it. "
Aa'ishah (radiallaahu anhu) reported that the Messenger of Allaah (sallallaahu alaihi wasallam) said: "The one who recites the Qur'an and is skilled in doing so will be with the obedient and noble angels and the one who recites the Qur'an in hesitance due to difficulty will receive a double reward."
Abdullaah bin Mas'ood (radiallaahu anhu) reported that the Messenger (sallallaahu alaihi wasallam) said: "Whoever recites one letter from the Book of Allaah then he will receive a good reward, and every good deed is rewarded with ten times its like. I do not say that Alif Laam Meem is one word but Alif is one word, Laam is one word and Meem is one word."
Abdullaah bin Amr ibn al-Aas reported that the Messenger of Allaah (sallallaahu alaihi wasallam) said: "It will be said to the one who had memorised the Qur'an [and acted upon it]: 'Recite the Qur'an (ascending the levels of Paradise thereby) and do so slowly and melodiously just as you used to recite slowly and melodiously in the world since your abode will be at the place where you finish reciting your last verse."
Nawwaas bin Sam'aan (radiallaahu anhu) reported that the Messenger of Allaah (sallallaahu alaihi wasallam) said: "The Qur'an and its people, those who used to act upon it in the world, will be brought on the Day of Judgement. However, Sooratul-Baqarah and Sooratul-Imraan will precede them and argue in favour of those who memorised and recited these soorah's (in this life)."
Umar ibn al-Khattaab (radiallaahu anhu) reported that the Messenger of Allaah (sallallaahu alaihi wasallam) said: "Verily, Allaah will raise elevate some people by this Book and He will degrade others with it."
Al-Bara' narrated: A man was reciting Surat Al-Kahf and his horse was tied with two ropes beside him. A cloud came down and spread over that man, and it kept oncoming closer and closer to him till his horse started jumping (as if afraid of something). When it was morning, the man came to the Prophet, and told him of that experience. The Prophet said, "That was As-Sakina (tranquility) which descended because of (the recitation of) the Qur'an." 
Usaid bin Hudair narrated: That while he was reciting Surat Al-Baqara (The Cow) at night, and his horse was tied beside him, the horse was suddenly startled and troubled. When he stopped reciting, the horse became quiet, and when he started again, the horse was startled again. Then he stopped reciting and the horse became quiet too. He started reciting again and the horse was startled and troubled once again. Then he stopped reciting and his son, Yahya was beside the horse. He was afraid that the horse might trample on him. When he took the boy away and looked towards the sky, he could not see it. The next morning he informed the Prophet who said, "Recite, O Ibn Hudair! Recite, O Ibn Hudair!" Ibn Hudair replied, "O Allah's Apostle! My son, Yahya was near the horse and I was afraid that it might trample on him, so I looked towards the sky, and went to him. Then I looked at the sky, I saw something like a cloud containing what looked like lamps, so I went out in order not to see it." The Prophet said, "Do you know what that was?" Ibn Hudair replied, "No." The Prophet said, "Those were Angels who came near to you for your voice and if you had kept on reciting till dawn, it would have remained there till morning when people would have seen it as it would not have disappeared."
