"The believer does not insult the honor of others, nor curse, nor commit Fahishah, nor is he foul."  

قَالَ رَسُولُ اللَّهِ ﷺ لَيْسَ الْمُؤْمِنُ بِالطَّعَّانِ وَلاَ اللَّعَّانِ وَلاَ الْفَاحِشِ وَلاَ الْبَذِيءِ  

"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
