Sahih Muslim Book 45, Hadith 101
" 'A'isha mounted upon a wild camel and she began to make that go round and round. Thereupon Allah's Messenger (ﷺ) said: You should show kindness, and then he made a mention of this hadith.
Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective.
We were with Allah's Messenger (ﷺ) in some of his journeys and there was a woman from the Ansar riding a she-camel that it shied and she invoked curse upon that. Allah's Messenger (ﷺ) heard it and said: Unload that and set it free for it is accursed. 'Imran said: I still perceive that (dromedary) walking amongst people and none taking any notice of that.
