The Mudabbar
Malik :: Book 41 : Hadith 41.3.15
Malik related to me from Nafi that a slave was in charge of the slaves in the khumus and he forced a slave-girl among those slaves against her will and had intercourse with her. Umar ibn al-Khattab had him flogged and banished him, and he did not flog the slave-girl because the slave had forced her.
