'Imran b. Husain reported
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.
'Imran reported
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."
Abu Burza al-Aslami reported that a slave-girl was riding a dromedary and there was also the luggage of people upon it. that she suddenly saw Allah's Apostle (ﷺ). The way of the mountain was narrow and she said (to that dromedary)
Go ahead (but that dromedary did not move). She (that slave-girl), out of anger, said: O Allah, let that (dromedary) be damned. Thereupon Allah's Apostle (ﷺ) said: Let the dromedary on which the curse has been invoked not proceed with us.
This hadith has been narrated on the authority of Sulaiman Taimi with the same chain of transmitters but with a variation of words (and that is)
" By Allah, let that accompany us not which has been damned, or he said like it."
Abu Huraira reported Allah's Messenger (ﷺ) as saying
It does not seem proper for a Siddiq that he should be an invoker of curse.
This hadith has been narrated on the authority of Abu Kuraib with the same chain of transmitters.
Zaid b. Aslam reported that 'Abd al-Malik b. Marwan sent some domestic goods for decoration to Umm Darda' on his own behalf, and when it was night 'Abd al-Malik got up and called for the servant. It seemed as if he (the servant) was late (in responding to his call), so he ('Abd al-Malik) invoked curse upon him, and when it was morning Umm Darda' said to him
I heard you cursing your servant during the night when you called him, and she said: I heard Abu Darda' as saying that Allah's Messenger (ﷺ) said: The invoker of curse would neither be intercessor nor witness on the Day of Resurrection.
This hadith has been narrated on the authority of Zaid b. Aslam with the same chain of transmitters.
Umm Darda' reported on the authority of Abu Darda' as saying
I heard Allah's Messenger (ﷺ) as saying: The invoker of curse would neither be witness nor intercessor on the Day of Resurrection.
Abu Huraira reported it was said to Allah's Messenger (ﷺ)
Invoke curse upon the polytheists, whereupon he said: I have not been sent as the invoker of curse, but I have been sent as mercy."
