Hadith 5811

He said that God's messenger was not unseemly in his language, or given to cursing or reviling. All he said when reproaching someone was, "What is the matter with him? May his forehead cleave to the dust!" Bukhari transmitted it.

وَعَنْهُ قَالَ: لَمْ يَكُنْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاحِشًا وَلَا لَعَّانًا وَلَا سَبَّابًا كَانَ يَقُولُ عِنْدَ الْمَعْتَبَةِ: «مَا لَهُ تربَ جَبينُه؟» . رَوَاهُ البُخَارِيّ
