Musannaf Ibn Abi Shayba 19:351

Abu Bakr narrated to us, he said: Mu'tamir ibn Sulayman al-Zurqi narrated to us, from Hajjaj, that an Abyssinian man forced a woman from among them [to have intercourse]. Umar ibn Abd al-Aziz established the prescribed punishment (hadd) upon him and gave her authority over his neck.
