question #3 Sahih al-Bukhari 6031, Book 78, Hadith 61 : What phrase did the Prophet Muhammad (ﷺ) use to express disapproval without cursing?

The Prophet (ﷺ) was not one who would abuse (others) or say obscene words, or curse (others), and if he
wanted to admonish anyone of us, he used to say: “What is wrong with him, his forehead be dusted!”
