narrated abdullah bin mas'ud (radi-allahu 'anhu):

the prophet (sallallahu 'alaihi wa sallam) 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 (sallallahu 'alaihi wa sallam) said, "enough for the present," i looked at him and behold! his eyes were overflowing with tears.
