Sunan Ibn Majah, Volume 5, Book 37, Hadith 4185 (DarusSalam) ⓘ
It was narrated from Anas that the Messenger of Allah said: “There is never any obscenity in a thing, but it mars it, and there is never any modesty in a thing, but it adorns it.”
حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا مَعْمَرٌ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " مَا كَانَ الْفُحْشُ فِي شَىْءٍ قَطُّ إِلاَّ شَانَهُ وَلاَ كَانَ الْحَيَاءُ فِي شَىْءٍ قَطُّ إِلاَّ زَانَهُ " .
