Shaxsni la'natlash haqida, u biror itoatsizlik qilgan taqdirda, masalan zolim, zinokor, surat chizuvchi, o'g'ri yoki riboxo'r bo'lsa, hadis dalillari bunday la'natlashning harom emasligini ko'rsatadi. Ammo G'azzoliy (va bu eng ishonchli qarash) la'natlash harom ekanini bildiradi, agar la'natlangan kishi kofir holda vafot etgani ma'lum bo'lmasa, masalan Abu Lahab, Abu Jahl, Fir'avn, Homon va ularga o'xshaganlar bundan mustasno. G'azzoliy bunga sabab qilib shuni aytadi: "La'nat qilish - boshqa birovni Allohning rahmatidan uzoqlashtirish demakdir, biz esa u buzuq kishi yoki kofir o'z umrini qanday yakunlashini bilmaymiz." Nabiy ﷺ shaxsan la'natlagan Ri'l, Zakvon va 'Usiya qabilalariga kelsak, ehtimol ular kufr holida o'lishlarini u zot bilganlari uchun shunday qilgandirlar.
Birovga yomonlik tilash la'natlashga o'xshaydi, hatto zolimga nisbatan bo'lsa ham, masalan "Alloh uni shifo bermasin", "Alloh uni saqlamasin" va shunga o'xshash so'zlar; bularning barchasi ayblanadi (agar musulmonga qaratilsa, harom hisoblanadi). Xuddi shunday, har qanday hayvonlarni yoki jonsiz narsalarni la'natlash ham ma'qul emas.
Shuning uchun olimlar aytadilar: "Kim la'natga loyiq bo'lmagan kishini la'natlasa, uni shunday deb tuzatsin: agar u la'natga loyiq bo'lsa." Yaxshilikka da'vat qiluvchi va yomonlikdan qaytaruvchi kishi birovga "voy sendan", "ey o'z nafsiga zulm qilgan" kabi so'zlar bilan murojaat qilishi joiz. Ammo yolg'on, tuhmat va g'iybatdan saqlanishi shart. Bundan tashqari, uning maqsadi odamlarni so'kish emas, balki nasihat qilish bo'lishi kerak.
As for cursing a particular person who commits some act of disobedience, such as an oppressor, adulterer, maker of pictures, the thief, or the one who consumes usurious gain; the hadith evidence seems to suggest that it is not unlawful, though Ghazali indicates (and it is the most reliable opinion) that is unlawful unless the person cursed is someone we know has died in a state of unbelief, such as Abu Lahab, Abu Jahl, Pharaoh, Haman, and others like them. This, Ghazali notes, is because "to curse means to distance another from the mercy of Allah Most High, while we do not know how the particular corrupt person or non-Muslim will end his life." As for those the Prophet (pbuh) personally cursed such as the tribes of Ri'la, Zakwan and 'Usiah, perhaps it was because he knew they would die in unbelief. Praying that evil befalls a person is similar to cursing, even when against a tyrant, such as saying, 'May Allah not heal him,' 'May Allah not keep him safe,' and similar remarks, all of which are blameworthy (being unlawful, if of a Muslim). And likewise for cursing any animals or inanimate objects whatever, all this is objectionable." The scholars therefore say, "Whoever curses someone who does not deserve so, let the former modify it by saying, if he deserves to be cursed.'" It is permissible for one who invites to good and forbids evil to address someone saying, "woe to you', "O you who have wronged his own self" and the like. Provided that he should avoid lying defamation, slander. Besides this, his objective should be admonishing and not insulting people.
