Hudayn ibn al-Mundhir AbuSasan reported: I saw that Walid was brought to Uthman ibn Affan as he had prayed two rak'ahs of the dawn prayer. He said: I
make an increase for you. And two men bore witness against him. One of them was Humran who said that he had drunk wine. The second one gave evidence
that he had seen him vomiting. Uthman said: He would not have vomited (wine) unless he had drunk it. He said: Ali, stand up and lash him. Ali said:
Hasan, stand up and lash him. Thereupon Hasan said: Let him suffer the heat (of Caliphate) who has enjoyed its coolness. (Ali felt annoyed at this
remark) and he said: Abdullah ibn Ja'far, stand up and flog him, and he began to flog him and Ali counted the stripes until these were forty. He
(Ali) said: Stop now, and then said: Allah's Apostle (peace be upon him) gave forty stripes, AbuBakr also gave forty stripes, and Umar gave eighty
stripes. All these fall under the category of the Sunnah, but this one (forty stripes) is dearer to me.
