We were with Messenger of Allah 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. Messenger of Allah 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. (Using translation from Muslim 2595a)  

بَيْنَمَا رَسُولُ اللهِ ﷺ فِي بَعْضِ أَسْفَارِهِ وَامْرَأَةٌ مِنَ الْأَنْصَارِ عَلَى نَاقَةٍ فَضَجِرَتْ فَلَعَنَتْهَا فَسَمِعَ ذَلِكَ رَسُولُ اللهِ ﷺ فَقَالَ خُذُوا مَا عَلَيْهَا وَدَعُوهَا؛ فَإِنَّهَا مَلْعُونَةٌ قَالَ عِمْرَانُ فَكَأَنِّي أَنْظُرُ إِلَيْهَا الْآنَ تَمْشِي فِي النَّاسِ مَايَعْرِضُ لَهَا أَحَدٌ يَعْنِي النَّاقَةَ  

[Machine] While the Messenger of Allah ﷺ was on one of his journeys, there was a woman from the Ansar riding a camel and it became restless, so she cursed it. The Messenger of Allah ﷺ heard this and said, "Take off what is on it and leave it, for it is cursed." Imran said, "I could see her wandering in the market and no one presenting anything to her." And perhaps he said, "the market of Medina."  

بَيْنَمَا رَسُولُ اللهِ ﷺ فِي بَعْضِ أَسْفَارِهِ وَامْرَأَةٌ مِنَ الْأَنْصَارِ عَلَى نَاقَةٍ فَضَجِرَتْ فَلَعَنَتْهَا فَسَمِعَ ذَلِكَ رَسُولُ اللهِ ﷺ فَقَالَ «خُذُوا مَا عَلَيْهَا وَدَعُوهَا فَإِنَّهَا مَلْعُونَةٌ» قَالَ عِمْرَانُ «فَكَأَنِّي أُرَاهَا تَجُولُ فِي السُّوقِ مَا يَعْرِضُ لَهَا أَحَدٌ» وَرُبَّمَا قَالَ سُوقُ الْمَدِينَةِ
