อัน-นิซาอ์ 4:148

<h2>The Permission to Utter Evil in Public, For One Who Was Wronged</h2><p>`Ali bin Abi Talhah said that Ibn `Abbas commented on the Ayah,</p><p>لاَّ يُحِبُّ اللَّهُ الْجَهْرَ بِالسُّوءِ مِنَ الْقَوْلِ</p><p>(Allah does not like that the evil should be uttered in public) "Allah does not like that any one should invoke Him against anyone else, unless one was wronged. In this case, Allah allows one to invoke Him against whoever wronged him. Hence Allah's statement,</p><p>إَلاَّ مَن ظَلَمَ</p><p>(except by him who has been wronged.) Yet, it is better for one if he observes patience." Al-Hasan Al-Basri commented, "One should not invoke Allah (for curses) against whoever wronged him. Rather, he should supplicate, `O Allah! Help me against him and take my right from him."' In another narration, Al-Hasan said, "Allah has allowed one to invoke Him against whoever wronged him without transgressing the limits." `Abdul-Karim bin Malik Al-Jazari said about this Ayah; "When a man curses you, you could curse him in retaliation. But if he lies about you, you may not lie about him.</p><p>وَلَمَنِ انتَصَرَ بَعْدَ ظُلْمِهِ فَأُوْلَـئِكَ مَا عَلَيْهِمْ مِّن سَبِيلٍ</p><p>(And indeed whosoever takes revenge after he has suffered wrong, for such there is no way (of blame) against them. )" …

Allah loveth not the utterance of harsh speech save by one who hath been wronged. Allah is ever Hearer, Knower.

Allah loveth not that evil should be noised abroad in public speech, except where injustice hath been done; for Allah is He who heareth and knoweth all things.

Allah does not like that the evil should be uttered in public except by him who has been wronged. And Allah is Ever All-Hearer, All-Knower.

God does not like the public uttering of bad language, unless someone was wronged. God is Hearing and Knowing.
