"Al-Fuhsh is not present in anything but it mars it, and Al-Haya' is not present in anything but it beautifies it."  

قَالَ رَسُولُ اللَّهِ ﷺ مَا كَانَ الْفُحْشُ فِي شَيْءٍ إِلاَّ شَانَهُ وَمَا كَانَ الْحَيَاءُ فِي شَيْءٍ إِلاَّ زَانَهُ وَفِي الْبَابِ عَنْ عَائِشَةَ  

"The best of you are those best in conduct.' And the Prophet was not one who was obscene, nor one who uttered obscenities."  

قَالَ رَسُولُ اللَّهِ ﷺ خِيَارُكُمْ أَحَاسِنُكُمْ أَخْلاَقًا وَلَمْ يَكُنِ النَّبِيُّ ﷺ فَاحِشًا وَلاَ مُتَفَحِّشًا
