Allah says in the Quran:
“And recite the Quran (aloud) in a (slow and melodious) style (tarteela)” [Quran 73:4]
The Messenger of Allah (ﷺ) said: "The one who recites the Qur'an and he is proficient with it, then he is with the noble and blessed Angels, and the one who recites it, and it is difficult for him, then he gets two rewards."
[Jami` at-Tirmidhi 2904]
The Prophet (ﷺ) said, "The best among you (Muslims) are those who learn the Qur'an and teach it."
[Sahih al-Bukhari 5027]
Allah's Messenger (ﷺ) said, "Whoever does not recite Qur'an in a nice voice is not from us," and others said extra," (that means) to recite it aloud."
[Sahih al-Bukhari 7527]
The Messenger of Allah (ﷺ) said: '"Make your voices beautiful when you recite Quran."
[Sunan an-Nasa'i 1016]
The Prophet (ﷺ) said, "The one who was devoted to the Qur'an will be told on the Day of Resurrection: 'Recite and ascend (in ranks) as you used to recite when you were in the world. Your rank will be at the last Ayah you recite."'
