وَلِمُسْلِمٍ: عَنْ عَلِيٍّ رضى الله عنه (فِي قِصَّةِ اَلْوَلِيدِ بْنِ عَقَبَةَ)
«جَلَدَ اَلنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَرْبَعِينَ، وَأَبُو بَكْرٍ أَرْبَعِينَ، وَعُمَرُ ثَمَانِينَ، وَكُلٌّ سُنَّةٌ، وَهَذَا أَحَبُّ»
Muslim transmitted on the authority of Ali (RAA) concerning the story of al-Walid ibn Uqbah that the Messenger of Allah (sallallahu alayhi wa sallam) inflicted forty lashes, Abu Bakr (RAA) forty lashes and Umar (RAA) eighty. All of them are in accordance with the Sunnah of the Prophet (sallallahu alayhi wa sallam) but this one (the eighty lashes) is preferable to me.
