Hāshim b. al-Qāsim > Shuʿbah > Qatādah > Anas

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. – Sound Chain

حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ حَدَّثَنَا شُعْبَةُ عَنْ قَتَادَةَ عَنْ أَنَسٍ

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» – إسناده صحيح
