The Answer

The answer: The insulting and cursing that are impermissible are those directed at the innocent, the righteous, and the believers, as well as that which is falsehood, slander, and fabrication.
As for distinguishing the one who is right from the one who is false, the truthful from the liar, and the disobedient from the obedient, and naming each according to what he deserves and judging him according to what Allah, Blessed and Exalted, has judged in the Qur’an—this is something required by the innate nature of reason and necessitated by the reality of faith.
For a reason Allah distinguished the human being with intellect and favored him over all other animals. And Allah the Exalted said to His Prophet (May Allah bless him and his family and grant them peace): “And do not obey every worthless habitual swearer, a slanderer, going about with malicious gossip, a preventer of good, a transgressor, a sinner, harsh and after that ignoble” [Al-Qalam:10–13]. Thus Allah the Exalted censured al-Walīd ibn al-Mughīrah al-Makhzūmī with the utmost censure—if it be correct to call that insult and abuse—for it is the utmost that can be inflicted and the furthest that can be said.
And He said, the Exalted: “Those who disbelieved from the Children of Israel were cursed by the tongue of David and Jesus son of Mary. That was because they disobeyed…” [Al-Māʾidah:78] to the end of the verses. And He said: “Indeed, the curse of Allah is upon the wrongdoers” [Hūd:18].
And He said: “Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Book—those are cursed by Allah, and cursed by those who curse” [Al-Baqarah:159].
And He said, while mentioning a people who opposed His command and disobeyed Him: “Those—upon them is the curse of Allah and the angels and the people, all together” [Al-Baqarah:161].
And how many instances there are in the Qur’an of cursing those who disobeyed the Lord of the worlds and opposed His command.
