Hazrat Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said to me: "Recite (the Qur'an)." So I began reciting Surah An-Nisa until I reached Allah's saying: "Then how will it be (with them) when We bring from every nation a witness, and We bring you (O Muhammad [peace and blessings be upon him] ) as a witness against these people?" He says: At that, tears were flowing from the eyes of the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "That is enough for you."
