Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective.  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الرِّفْقَ لاَ يَكُونُ فِي شَىْءٍ إِلاَّ زَانَهُ وَلاَ يُنْزَعُ مِنْ شَىْءٍ إِلاَّ شَانَهُ  

[Machine] "He heard her saying, 'I was riding a difficult camel, so I started hitting it.' Then the Messenger of Allah ﷺ said to me, 'Be gentle, for gentleness beautifies everything and is not removed from anything without spoiling it.'"  

أَنَّهُ سَمِعَهَا تَقُولُ كُنْتُ عَلَى بَعِيرٍ صَعْبٍ فَجَعَلْتُ أَضْرِبُهُ فَقَالَ لِي رَسُولُ اللهِ ﷺ عَلَيْكِ بِالرِّفْقِ فَإِنَّ الرِّفْقَ لَا يَكُونُ فِي شَيْءٍ إِلَّا زَانَهُ وَلَا يُنْزَعُ مِنْ شَيْءٍ إِلَّا شَانَهُ  

[Machine] Aisha rode a camel and it was difficult for her, so she started complaining. The Messenger of Allah ﷺ said to her, "Be gentle, for verily, gentleness is not in anything except that it beautifies it, and it is not removed from anything except that it tarnishes it."  

رَكِبَتْ عَائِشَةُ بَعِيرًا فَكَانَ مِنْهُ صُعُوبَةٌ فَجَعَلَتْ تُرَدِّدُهُ فَقَالَ لَهَا رَسُولُ اللهِ ﷺ عَلَيْكِ بِالرِّفْقِ فَإِنَّهُ لَا يَكُ فِي شَيْءٍ إِلَّا زَانَهُ وَلَا يُنْزَعُ مِنْ شَيْءٍ إِلَّا شَانَهُ  

Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective. (Using translation from Muslim 2594a)   

"إِنَّ الرِّفْقَ لا يَكُونُ فيِ شيءٍ إِلَّا زَانَهُ، وَلَا نُزع مِن شيءٍ إِلَّا شَانَهُ".  

"مَا كَانَ الرِّفْقُ فِي شَيْءٍ إلَّا زَانَهُ ولا نُزِعَ مِنْ شيءٍ إِلَّا شَانَهُ".  

"يَا عَائِشَةُ: عَلَيْكِ بِتَقْوَى الله وَالرِّفْقِ، فَإِنَّ الرِّفْقَ لَمْ يَكُنْ فِى شَئٍ قَطُّ إِلَّا زَانَهُ وَلَا نُزعَ مِنْ شَىْءٍ قَطُّ إِلَّا شَانَهُ".
