Sahih Bukhari Volume 6, Book 61, Hadith Number 570.

Narrated By Abdullah bin Mas’ud : The Prophet said to me, “Recite (the Quran) to me.” I said, “O Allah’s Apostle Shall I recite (the Qur’an) to you while it has been revealed to you?” He said, “Yes.” So I recited Surat-An-Nisa’ (The Women), but when I recited the Verse:

‘How (will it be) then when We bring from each nation a witness and We bring you (O Muhammad) as a witness against these people.’ (4.41) He said, “Enough for the present,” I looked at him and behold! His eyes were overflowing with tears.
