That a man who had drunk wine was brought to the Prophet ﷺ, so he beat him about forty times with two stalks of a palm tree. So Abu Bakr did similarly, and by the time 'Umar became Khalifah he sought council from the people. And 'Abdur-Rahman bin 'Awf said: 'I see that the lightest penalty is eighty lashes,' so 'Umar ordered that. (Using translation from Tirmidhī 1443)   

أَنَّ النَّبِيَّ ﷺ «أُتِيَ بِرَجُلٍ قَدْ شَرِبَ خَمْرًا فَضَرَبَهُ بِجَرِيدَتَيْنِ» ثُمَّ فَعَلَ أَبُو بَكْرٍ مِثْلَ ذَلِكَ فَلَمَّا كَانَ عُمَرُ اسْتَشَارَ النَّاسَ فَقَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ أَخَفُّ الْحُدُودِ ثَمَانِينَ قَالَ «فَفَعَلَ»  

“When Walid bin ʿUqbah was brought to ʿUthman, they had testified against him. He said to 'Ali: 'You are close to your uncle's son, so carry out the legal punishment on him.' So 'Ali whipped him. He said: 'The Messenger of Allah ﷺ gave forty lashes, and Abu Bakr gave forty lashes, and 'Umar gave eighty all are Sunnah.'” (Using translation from Ibn Mājah 2571)   

عَلِيٌّ «جَلَدَ النَّبِيُّ ﷺ أَرْبَعِينَ وَجَلَدَ أَبُو بَكْرٍ أَرْبَعِينَ وَعُمَرُ ثَمَانِينَ وَكُلٌّ سُنَّةٌ»
