Musnad Ahmad 26:4

Hushaym narrated to us, Mughirah informed us, from Abu Razin, from Ibn Mas’ud, who said: I recited to the Messenger of Allah, may Allah bless him and grant him peace, from Surat an-Nisa’. When I reached this verse: {So how [will it be] when We bring from every nation a witness and We bring you, [O Muhammad], against these as a witness?} [An-Nisa’: 41], he said: "His eyes overflowed," may Allah bless him and grant him peace.
