[Machine] While you are like this, he said, "No, you have become weak and tired, O Abdullah ibn Jafar. Get up and whip him." So Ali started whipping him, counting until he reached forty. He then said, "Stop, the Messenger of Allah ﷺ whipped forty, Abu Bakr whipped forty, and Umar whipped eighty, and each is a Sunnah." And Abu Muhammad informed us, who informed us Abu Sa'eed, who narrated from Az-Za'farani, who narrated from Yazid ibn Harun, who narrated from Sa'eed, who narrated from Abdullah Ad-Danaji, who narrated from Hudhayn ibn Al-Mundhir ibn Al-Harith ibn Wa'lah, that Al-Walid ibn Uqbah prayed Fajr with the people four rak'ahs, then turned to them and said, "Should I increase upon you?" This was then conveyed to Uthman, who mentioned something similar to it, except in the hadith of Yazid, it mentions that the Messenger of Allah ﷺ whipped forty, and Abu Bakr and Umar did the same, during the beginning of their caliphates, and Umar continued with eighty, and each is a Sunnah.
