Sahih Muslim Book 4, Hadith Number 1750.

Chapter : Excellence of the reciting of the Qur’an by one who is more skilled and proficient before one who is inferior to him.

‘Abdullah (b. Mas’ud) reported: The Messenger of Allah (may peace be upon (him) asked me to recite the Qur’an. He said: Messenger of Allah, (how) should I recite to you whereas it has been sent down to you? He (the Holy Prophet) said: I desire to hear it from someone else. So I recited Surat Al-Nisa’ till I reached the verse: How then shall it be when We shall bring from every people a witness and bring you against them as a witness?” (verse 41). I lifted my head or a person touched me in my side, and so I lifted my head and saw his tears falling (from the Holy Prophet’s eyes).
