The Shaykh’s remarks on the issue of cursing a specific Muslim who has committed an act deserving of a curse

The Shaykh : And they differed even more intensely on the issue of cursing a specific Muslim by name if he commits an act that deserves a curse. The majority of them also said that it is not permissible. However, the reality is that 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 we have passed by this story in the book, either in the book itself or as a commentary on some of the hadiths. It is a story that contains one of the gentle methods 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 and blessings be upon him) approved of them doing so. The reality is that the result of this method of reviling and cursing the oppressor was that he was deterred from his oppression.
The rebel who is oppressive. In this, some of the Companions used the word "curse" regarding that oppressive tyrant, and the Messenger of Allah (peace and blessings be upon him) approved of them doing so. In reality, the result of this approach of cursing and invoking curses upon the oppressor was that he desisted from his oppression.
The summary of that story is that a man came to the Messenger (peace and blessings be upon him) complaining about his neighbor. He (peace be upon him) ordered him to be patient, so he was patient, then... he was patient, and he returned to the Messenger (peace and blessings be upon him) complaining about him, and so on. When the Messenger (peace and blessings be upon him) learned that this neighbor was being wronged and harmed, the Messenger (peace and blessings be upon him) said to him: So he did it. Without a doubt, this throwing... and to draw their attention and prompt them to ask, "What is wrong with you, so-and-so?" And all he would say is, "So-and-so, my neighbor, has wronged me." And all they would say is, "May Allah kill him, may Allah curse him." The neighbor would hear with his own ears, so he hastened to the Prophet (peace and blessings be upon him) repentant, desiring to return his neighbor's belongings to his house. Such an incident indicates to us that cursing the oppressor specifically, as a means of disciplining him, is permissible. But this is done with this intention and for this purpose. Therefore, the ruling on the hadith of this chapter remains complete in the Shari'ah. It is not befitting for a believer to be one who curses, meaning that the word "curse" must never come out of his mouth, and likewise, of course, all vulgar and unpleasant words.
