" That (this) is indeed an honourable recital (the Noble Quran). "
[Al-Waaqiaah 56:77]

"Verily, We have sent down to you (O Muhammad) the Book (this Quran) for mankind in truth. So whosoever accepts the guidance, it is only for his ownself; and whosoever goes astray, he goes astray only for his (own) loss. And you (O Muhammad) are not a Wakeel (trustee or disposer of affairs, or guardian) over them"
[Al-Zumar 39:4]

"And (it is) a Quran which We have divided (into parts), in order that you might recite it to men at intervals. And We have revealed it by stages."
[Al-Israa 17:106]

"And We have sent down to you the Book (the Quran) as an exposition of everything, a guidance, a mercy, and glad tidings for those who have submitted themselves (to Allah as Muslims)"
[Al-Nahl 16:89]

Uthman bin Affan (may Allah be pleased with him) narrated that the Prophet (peace be upon him) said, "The most superior among you (Muslims) are those who learn the Quran and teach it."
[Bukhari: Book 61: Hadith 546]
