The Shaykh:
There is a distinction here. Cursing disbelievers in general, and cursing the perpetrators of major crimes for which evidence has been provided to curse their perpetrators, is done by way of generality, such as “The curse of Allah is upon the wrongdoers,” and so on. So we say “The curse of Allah is upon the liars,” meaning by way of generality. As for a specific person, a particular individual, there is disagreement on whether it is permissible to curse him or not. The correct view is that it is not permissible to curse a specific person, because you do not know what his outcome or his end will be. Yes, as for ruling that he is in the Fire, you do not know.
