Sahih Muslim Book 45, Hadith 102
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.
" '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.
I perceive as if I am looking towards that dromedary, and in the hadith transmitted on the authority of Thaqafi (the words are):" Unload it and make its back bare for it is accursed."
