Narrated As-Sa'ib bin Yazid:
حَدَّثَنَا مَكِّيُّ بْنُ إِبْرَاهِيمَ ، عَنِ الْجُعَيْدِ ، عَنْ يَزِيدَ بْنِ خُصَيْفَةَ ، عَنِ السَّائِبِ بْنِ يَزِيدَ ، قَالَ كُنَّا نُؤْتَى بِالشَّارِبِ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَإِمْرَةِ أَبِي بَكْرٍ وَصَدْرًا مِنْ خِلاَفَةِ عُمَرَ، فَنَقُومُ إِلَيْهِ بِأَيْدِينَا وَنِعَالِنَا وَأَرْدِيَتِنَا، حَتَّى كَانَ آخِرُ إِمْرَةِ عُمَرَ، فَجَلَدَ أَرْبَعِينَ، حَتَّى إِذَا عَتَوْا وَفَسَقُوا جَلَدَ ثَمَانِينَ.
We used to strike the drunks with our hands, shoes, clothes (by twisting it into the shape of lashes) during the lifetime of the Prophet, Abu Bakr and the early part of `Umar's caliphate. But during the last period of `Umar's caliphate, he used to give the drunk forty lashes; and when drunks became mischievous and disobedient, he used to scourge them eighty lashes.
