Muwatta Malik, Book 41, Hadith 15 (USC-MSA)

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.

حَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، أَنَّ عَبْدًا، كَانَ يَقُومُ عَلَى رَقِيقِ الْخُمُسِ وَأَنَّهُ اسْتَكْرَهَ جَارِيَةً مِنْ ذَلِكَ الرَّقِيقِ فَوَقَعَ بِهَا فَجَلَدَهُ عُمَرُ بْنُ الْخَطَّابِ وَنَفَاهُ وَلَمْ يَجْلِدِ الْوَلِيدَةَ لأَنَّهُ اسْتَكْرَهَهَا ‏.‏
