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!"
لَمْ يَكُنِ النَّبِيُّ ﷺ سَبَّابًا وَلاَ فَحَّاشًا وَلاَ لَعَّانًا كَانَ يَقُولُ لأَحَدِنَا عِنْدَ الْمَعْتَبَةِ مَا لَهُ تَرِبَ جَبِينُهُ
