The ruling on specifying by name those who have earned the curse due to their disbelief and open sinfulness, such as al-Tusi

Question : A decision. We are among those who... but it cannot be.

Answer : Yes, it is not permissible to specify by name. Because when the Messenger (peace and blessings be upon him) began cursing specific individuals, Allah forbade him from doing so. Perhaps if he specifies someone who has died upon something that warrants the curse, he might be saved. Also, the scholars' action is not a proof; the proof is what Allah and His Messenger said. And what is the benefit of this? You can respond to him without cursing. You do not respond by cursing the one who is cursed who said such-and-such, or the one who is cursed who did such-and-such. They do not accept a response like that.
I told you that sometimes a person, in a state of agitation, may utter words, and upon reflection, he might not have said them. No, I do not see this. And although I hold that al-Tusi is cursed without a doubt. Yes.
The truth, my brothers, is what is the benefit of cursing? And perhaps Ibn al-Qayyim means by the cursed one the one who is far from the mercy of Allah and from the satisfaction of the people toward him, because the Messenger (peace and blessings be upon him) said: He said: He insults the man's father, and the man insults his father, so the insult was made a curse.
