Musnad Ahmad 1013:78

Husayn ibn Muhammad narrated to us, Muslim narrated to us, from 'Abbad ibn Ishaq, from Abu Hazim, Sahl ibn Sa'd narrated to me, that a man from Aslam came to the Prophet, may Allah bless him and grant him peace, and said: "He has committed adultery with a woman," and he named her. The Prophet, may Allah bless him and grant him peace, sent for the woman and summoned her. He asked her about what he had said, and she denied it. So he applied the prescribed punishment (hadd) to him and left her.
