Musannaf Ibn Abi Shaybah 30803 — Discretionary punishment (ta'zir)

Al-Harith bin Utbah said that a man who used to revile Sayyiduna Uthman (may Allah be pleased with him) was brought to Umar bin Abd al-Aziz. He asked: "What drove you to revile him?" The man said: "I hate him." They said: "If you hate a man, does that mean you revile him?" So, on his order, he was given thirty lashes.
