Muwatta Malik, Book 42, Hadith 1540 (In-Book)

Yahya related to me from Malik from Ibn Shihab that as-Sa'ib ibn Yazid informed him that Umar ibn al-Khattab came out to them. He said, "I have found the smell of wine on so-and-so, and he claimed that it was the drink of boiled fruit juice, and I am inquiring about what he has drunk. If it intoxicates, I will flog him." Umar then flogged him with the complete hadd.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنِ السَّائِبِ بْنِ يَزِيدَ، أَنَّهُ أَخْبَرَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ خَرَجَ عَلَيْهِمْ فَقَالَ إِنِّي وَجَدْتُ مِنْ فُلاَنٍ رِيحَ شَرَابٍ فَزَعَمَ أَنَّهُ شَرَابُ الطِّلاَءِ وَأَنَا سَائِلٌ عَمَّا شَرِبَ فَإِنْ كَانَ يُسْكِرُ جَلَدْتُهُ ‏.‏ فَجَلَدَهُ عُمَرُ الْحَدَّ تَامًّا ‏.‏
