Musannaf Ibn Abi Shaybah 30109 — Those who said a slave receives

Jarir bin Hazim reports: I read the letter of Umar bin Abd al-Aziz to Adi bin Artah: "After praise and salutations: You have asked about the slave who makes a vile accusation against a free person, how many lashes he is to be given. You mentioned that it reached you that when I was in Madinah I gave the slave forty lashes, and that then, at the end of my term, I gave him eighty lashes. My first lashing was an opinion I had formed, and the lashing I gave at the end of my term was in agreement with the Book of Allah. So you too should give him eighty lashes."
