Discussion of the issue of cursing a specific Muslim who has committed an act that warrants cursing.

The Shaykh : They differed even more intensely on the issue of cursing a specific Muslim by name if he commits an act that warrants cursing. The majority of them said, likewise: it is not permissible. However, in reality, we see in the Sunnah what testifies to the permissibility of cursing a specific oppressor as a means of disciplining him and deterring him from his oppression. I think this story has passed by us in the book, either in the book itself or as a commentary on some of the hadiths. It contains a subtle method of the Messenger (peace and blessings be upon him) in educating the rebellious oppressor. In it, some of the Companions used the word "curse" regarding that unjust oppressor, and the Messenger (peace be upon him) approved of them doing so. In fact, the result of this method of reviling and cursing the oppressor was that he desisted from his oppression.
The summary of that story is that a man came to the Prophet (peace and blessings be upon him) to complain about his neighbor. He (peace be upon him) ordered him to be patient, so he was patient. Then his patience ran out, and he returned to the Messenger (peace be upon him) complaining about him, and so on. When he (peace and blessings be upon him) knew that this neighbor was being wronged and harmed, he said to him (peace be upon him): . So he did it. There is no doubt that this throwing out—meaning, one takes the contents of his house and puts them on the road—is a matter that attracts people's attention, draws their eyes, and prompts them to ask: "What is wrong with you, so-and-so?" So he can only say: "So-and-so, my neighbor, has wronged me." And they can only say: "May Allah kill him! May Allah curse him!" So it became the talk of the passersby: "May Allah kill him, may Allah curse him!" The neighbor heard it with his own ears, so he hastened to the Prophet (peace and blessings be upon him) repentant, desiring that his neighbor's belongings be returned to his house, for it had ended... So an incident like this indicates to us that cursing a specific oppressor as a means of disciplining him is permissible. But this is done with this intention and for this purpose. The discussion of this chapter remains clear, its ruling continuing in the Shari'ah. It is not befitting for a believer to be a cursing person; meaning, the word "curse" is constantly coming from his mouth, and of course, all ugly and obscene words are like that.
