Cursing is dispraised whether it be directed towards another human being, or an animal, or inanimate thing. Allah’s Messenger, peace be upon him, said: ‘A believer is not a curser.’2J He, peace be upon him, also said: ‘Do not curse one another with Allah’s damnation, nor with His wrath, nor with Gehenna.’
‘Imrän ibn I-Jusayn said: ‘While Allah’s Messenger, peace be upon him, was on one of his travels, a woman from the Medinan Helpers [who was among those accompanying him] became fed up with her camel and, hence, cursed it. Upon hearing her, the Prophet, peace be upon him, said: ‘Take what’s on it [the camel] and denude it, for it is cursed “’ ‘lmrän ibn I-Jusayn said: ‘It was as if I could look at that camel walking among people without being obstructed by anyone.
The Prophet, peace be upon him, also said: ‘The cursers are not going to be intercessors on the Day of Judgement, nor are they going to be witnesses.’
Cursing (al-la’n) is repulsion and expulsion from Allah, exalted is He. Hence it is not allowed against anyone other than one who has traits which repulse him from Allah, glorified is He, and these traits are unbelief and transgression. And even then one should use the expression ‘May Allah’s curse be on the unbelievers and the transgressors’. There are three traits which require that they be cursed: namely, unbelief, blameworthy innovation and offence. Allah’s Messenger, peace be upon him, said: ‘The one who curses a believer is as if he has killed him. Of a similar nature to cursing is imploring Allah that something evil befalls a person.
