Musannaf Ibn Abi Shaybah 30335 — A man who says to another: You wine

Sulayman bin Musa said: We asked Umar bin Abd al-Aziz about a man who says to a man: O drinker of wine, or O polytheist, or O drunkard. We asked: Is he to be punished? He said: Subhan Allah (Glory be to Allah)! No one is to be punished except the one who falsely accuses a Muslim.
