Muwatta Malik 1539

وَحَدَّثَنِي عَنِ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ سُئِلَ عَنْ حَدِّ الْعَبْدِ، فِي الْخَمْرِ فَقَالَ بَلَغَنِي أَنَّ عَلَيْهِ نِصْفَ حَدِّ الْحُرِّ فِي الْخَمْرِ وَأَنَّ عُمَرَ بْنَ الْخَطَّابِ وَعُثْمَانَ بْنَ عَفَّانَ وَعَبْدَ اللَّهِ بْنَ عُمَرَ قَدْ جَلَدُوا عَبِيدَهُمْ نِصْفَ حَدِّ الْحُرِّ فِي الْخَمْرِ ‏.‏

Yahya related to me from Malik from Ibn Shihab that he was asked about the hadd of the slave for wine. He said, "I heard that he has half the hadd of a freeman for drinking wine. Umar ibn al-Khattab, Uthman ibn Affan, and Abdullah ibn Umar flogged their slaves with half of the hadd of a freeman when they drank wine
