Sahih Muslim , Book 45, Hadith 100 (In-Book) ⓘ
'A'isha, the wife of Allah's Apostle, reported Allah's Apostle as saying: Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective.
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنِ الْمِقْدَامِ، - وَهُوَ ابْنُ شُرَيْحِ بْنِ هَانِئٍ - عَنْ أَبِيهِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ الرِّفْقَ لاَ يَكُونُ فِي شَىْءٍ إِلاَّ زَانَهُ وَلاَ يُنْزَعُ مِنْ شَىْءٍ إِلاَّ شَانَهُ " .
