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.
Muwatta Malik Book 41, Hadith 15
