وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ ثَوْرِ بْنِ زَيْدٍ الدِّيلِيِّ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، اسْتَشَارَ فِي الْخَمْرِ يَشْرَبُهَا الرَّجُلُ فَقَالَ لَهُ عَلِيُّ بْنُ أَبِي طَالِبٍ نَرَى أَنْ تَجْلِدَهُ ثَمَانِينَ فَإِنَّهُ إِذَا شَرِبَ سَكِرَ وَإِذَا سَكِرَ هَذَى وَإِذَا هَذَى افْتَرَى ‏.‏ أَوْ كَمَا قَالَ فَجَلَدَ عُمَرُ فِي الْخَمْرِ ثَمَانِينَ ‏.‏

Yahya related to me from Malik from Thawr ibn Zayd ad-Dili thatUmar ibn al-Khattab asked advice about a man drinking wine. Ali ibnAbi Talib said to him, "We think that you flog him for it with eightylashes. Because when he drinks, he becomes intoxicated, and when hebecomes intoxicated, he talks confusedly, and when he talksconfusedly, he lies." (80 lashes is the same amount as for slandering)Umar gave eighty lashes for drinking wine. Translation Not Available
