Musannaf Ibn Abi Shayba 19:892

Abu Bakr narrated to us, he said: Shareek narrated to us, from ‘Abd al-Malik ibn ‘Umayr, he said: ‘Ali said: Regarding a man saying to a man, "O wicked one, O corrupt one," he said: They are obscenities, and in them is a punishment. Do not say them, lest you become accustomed to them.
